A crewman on a commercial tuna-fishing boat was the first to spot it: something shiny and metallic in the water off the ship's bow. The crewman alerted the navigator, and the 280-foot San Nikunau slightly altered course to avoid a collision. As the ship came closer, the object revealed itself to be a small boat, an aluminum dinghy. It was late in the afternoon on November 24 of last year. The New Zealand–based San Nikunau was in open water, a couple of days out of Fiji, amid the vastness of the southern Pacific—an expanse the size of a dozen Saharas in which there are only scattered specks of land.

The dinghy, fourteen feet long and low to the water, was designed for traveling on lakes or hugging a shoreline. There was no way it should've been in this part of the Pacific. If the San Nikunau had passed a quarter mile to either side, likely no one would have noticed it. Anyway, it appeared empty, another bit of the ocean's mysterious flotsam. But then, as the big ship was approaching the dinghy, something startling happened. From the bottom of the tiny boat, emerging slowly and unsteadily, rose an arm—a single human arm, skinny and sun-fried and waving for help.

There were, as it turned out, three people on the boat. Three boys. Two were 15 years old and the third was 14. They were naked and emaciated. Their skin was covered with blisters. Their tongues were swollen. They had no food, no water, no clothing, no fishing gear, no life vests, and no first-aid kit. They were close to death. They had been missing for fifty-one days.

It began, in the grand tradition of ill-considered ideas, with a group of boys and a bottle of booze—the most common of circumstances in the least common of places. The boys were gathered in their clubhouse—broken sofas, graffitied walls—near the end of the only road in the only village on the Pacific island of Atafu. Atafu is one of three atolls that make up the nation of Tokelau (which is not, technically, a nation but a territory of New Zealand). The total amount of land on Atafu is 1.4 square miles. Population: 524.

The nearest atoll, equally tiny, is fifty-seven miles to the south, well beyond the range of visibility. The closest significant land mass is Samoa, a twenty-eight-hour ferry ride away. There is no landing strip on Tokelau. There are also no dogs, prisons, lawyers, pavement, or soil—the land is mostly bits of broken coral. The highest elevation is fifteen feet. Coconuts and fish are the traditional diet, though the ferry, which comes once every two weeks, brings so much junk food these days that obesity and diabetes have become significant problems. From any point on Atafu's shoreline, nothing can be seen but water, all the way to the horizon.

One of the boys in the clubhouse—by most accounts, the unofficial leader—was named Filo Filo. (It's not uncommon in Tokelau to have the same first and last names.) Filo was tall and strong and exceptionally athletic. His dream was to play for the New Zealand All Blacks. Though his parents were both Tokelauan, Filo had lived his entire life away from the islands, mostly in Sydney, Australia, where his mother had moved after she'd separated from Filo's father. But in 2007, Filo's mother grew concerned about his poor grades and growing reputation as a troublemaker. As a sort of reform school, she sent him to Atafu to live with his dad, who in addition to being a fisherman—the profession of nearly every Tokelauan man—was also the local rugby coach. Filo became a star athlete on Atafu, but some people still thought of him, to use the Tokelauan word, as a palagi—a foreigner. One classmate called him a "wanna-be gangster." He was, in truth, a city kid who had been exiled to one of the tiniest and most remote places on the planet.

Filo had become best friends with a boy named Samu Tonuia. They were both 15 and in the same class at school—a class of seven students. Samu, like Filo, was tall and muscular for his age and also an excellent rugby player. Otherwise, the two boys could not have been more different. Samu had never once in his life left Tokelau. It is customary in Tokelau to assign one child to care for elderly relatives, and while the rest of his family had moved to Australia, Samu lived on Atafu with his grandmother. He'd never been in an airplane or a restaurant or a movie theater. According to one classmate, Samu had been a decent student—until Filo arrived.

So there they were, Filo and Samu, the permanent foreigner and the ultimate local, a gang of two, sitting in their clubhouse along with a handful of other boys. It was October 3, 2010. They were drinking vodka, smoking cigarettes, telling stories. It was getting late.

Then someone brought up the tale of the teenagers. Five or six years previous, three teens had taken a boat without permission and broken one of the cardinal rules of Tokelauan society: They'd ventured into the open ocean without the escort of a tautai, a master fisherman. Atafu's forty-two small islands encircle a gorgeous turquoise lagoon in which anyone can boat or swim. It's the kiddie pool. The ocean is an unpredictable and occasionally violent place, and the title of tautai, bestowed by the island's elders, is equivalent to a driver's license. Even tautais do not venture far offshore.

But to teenage boys, in Atafu as in every pocket of the planet, rules are made to be broken. And the isolation of Atafu can at times be difficult to bear. There's now satellite Internet service on the island, which only emphasizes how much fun everyone else is having. Filo told me that Atafu "felt like a prison." The desire to escape can become overwhelming.

Which is what those teenagers did five or six years ago. They escaped, trying to reach some other place. Any other place. They didn't make it. They were rescued after five days by the Tokelau ferry. They'd run out of gas but had plenty of food. Though they were severely punished by the elders, in Filo and Samu's clubhouse they were heroes. And as a plastic jug of vodka was passed around, the old story soon morphed into a new idea. By the time the jug was finished, the idea had become a plan.

Etueni Nasau was also in the clubhouse. He'd listened intently to the story but had passed on the vodka. He wasn't much of a drinker. Etueni (his name is pronounced ed-ween-aye) was, at 14, a year younger than Samu and Filo and a grade lower in school. He was also much smaller and not nearly as athletic. When I asked all three boys what they wanted to be when they grew up, Filo said "rugby player" and Samu said "rugby player" and Etueni said "surgeon." Etueni was neither an outsider, like Filo, nor an insider, like Samu, but somewhere in between. He was born in New Zealand, spent his early childhood in Atafu, went to school in American Samoa, and then moved full-time to Atafu in 2008.

Hearing the story of the teens sparked something in Etueni. He'd always been a good student, a well-behaved boy. But he, too, was often frustrated with the truncated boundaries of life on a tiny atoll, his one square mile of world. "Its freekin hell" he once posted on Facebook. He also yearned to be more popular, to be thought of by the others in the clubhouse as a hero rather than a nerd. To have a grand adventure. And so almost on a whim, when the plans became serious—when Samu announced he'd be willing to steal his uncle's new boat—and most everyone in the clubhouse began backpedaling from their bluster, Etueni finally spoke up. He said he was in.

It was now past midnight. The rest of the boys headed home. Filo, Samu, and Etueni fanned out across the village. Their first mission was to find gasoline, and they soon collected about twenty gallons in five plastic jerry cans. They stashed the stolen gas in Samu's uncle's boat, a silver-colored Frewza, made in New Zealand, with a fifteen-horsepower Yamaha engine. There was nothing fancy about it—a couple of unpainted wooden benches, a tiny storage space in the bow that could keep a few things dry. The only items inside were a small machete and a wooden mallet, used to club fish. Its freeboard—the distance between the water and the top of the boat's sides—was just sixteen inches, enough to repel only the smallest of waves. The boat's best feature was not visible: Inside the hull were three large air-filled aluminum cylinders, pontoons that made the craft exceptionally stable.

After loading the gas, the boys again separated, dashing the short distance from the dock to the village. Filo sneaked into his house and grabbed a green tarpaulin, a large plastic sack containing twenty coconuts, a white ceramic teacup, two packs of Pall Mall cigarettes, and another jug of vodka, still sealed. From his refrigerator, he took two bottles of milk and a Kraft mayonnaise jar filled with water. Samu, meanwhile, climbed a tree and knocked down nine more coconuts. Etueni had been instructed to find fishing equipment, but he was concerned that he'd wake someone up and get caught. So there was no fishing gear.

The boys boarded the boat. To steel their resolve, they opened the vodka, poured it in the teacup, added a bit of water, and passed it around. This time, Etueni joined in. Samu started the engine. It was the final chance to run home, to sleep in a bed. Etueni later admitted to me that as he sat in the boat, he'd thought that this was a dangerous and stupid idea. "I almost jumped off," he says. But then Filo began yelling, and Samu and Etueni joined in—a rebel yell, a primal scream. A howl that tried to both express and eclipse their nervous, excited joy. They soon began shouting people's names, those they'd stolen from. They teased Samu's uncle. "Ha-ha! We're leaving! We stole your boat!" And they motored through the gap in the reef surrounding Atafu. It was the first time any of the boys had been on the ocean side of Tokelau without a master fisherman. Their plan, they later told me, was to reach the next atoll. They figured it would take three or four days. They had only the clothes they wore: shorts and T-shirts and sandals. No one wore a cap. No one had remembered to bring sunglasses.

They continued drinking. Etueni was bartender—water and vodka, in their one tea cup. Filo was the first to tire out; he curled up on the bottom of the boat. Samu and Etueni stayed up, still drinking. Somehow, in his insobriety, Etueni took off his shirt and lost it overboard. Samu controlled the engine. "We just had an idea of following one star," says Etueni. "But we didn't know what star it was." Then Samu, too, grew sleepy. So Etueni drove for a while. Eventually he switched off the engine. And soon all three boys were passed out on the flat metal bottom of the boat.

They were cold in the night. Cold and wet. Waves and spray continually spilled into the boat. The puddle in the bottom was soon up to their ears. Etueni woke first, to the noise of a couple of dozen seagulls flying around. He could no longer see land. The bright sun, he realized, eliminated the idea of following one star. Filo was next up. He immediately vomited over the side. Then Samu awoke, and he, too, threw up.

Samu revved the engine. "We just started going," says Filo. Where? "Just anywhere." They were not worried. "We thought we were going to be fine," Etueni says. "The other boys were found in five days."

They began cracking coconuts, banging them against the rail of the boat, drinking the liquid, and chucking them away. They didn't even bother scraping out the coconut meat. Then they finished both bottles of milk. They broke out the cigarettes. Only six were dry. They smoked them.

They ran the engine intermittently. It was a warm and overcast day. Their new idea was to follow the seagulls; in the evening, they figured, the birds would naturally head back to land. But the birds seemed to be flying randomly, maybe in big circles.

As the afternoon wore on, they grew a little hungry. They wondered what people were saying about them back on Atafu. Eventually the sun set. "We were still in a good mood," says Filo. "Not that hungry." They slept again in a puddle on the bottom of the boat.

The next day, they saw an airplane. It was flying low, and they figured it was looking for them. Etueni waved, and the other two boys immediately teased him for wanting to be rescued so soon. "You're a girl," they said. So he stopped waving. Filo and Samu didn't think two days was enough to seem heroic. They figured, as the plane flew away, that it would eventually be back.

When there's an emergency on Atafu, the secretary of the men's group walks the coral-gravel road blowing on a brass bugle, strolling past the small, brightly painted homes made of concrete with corrugated-steel roofs. He did this on the morning after the boys left, summoning everyone to Atafu's meeting hall.

The leader of all of Tokelau is called the ulu; the position rotates every year among the heads of each individual atoll, and when the boys left, it was Atafu's turn. The ulu, Kuresa Nasau, immediately ordered all the village men to check the lagoon and the outer islands. He contacted the leaders of the other two atolls, and they, too, sent their men out.

The prevalent feeling on Atafu, according to a nurse who works in the island's medical clinic, was "Oh no, not again." The island was still recovering from a tragedy eight months earlier, in February of 2010, when three men on a barge were caught in a storm. Their boat capsized. The bodies washed ashore. And now three more were missing. The forecast was for stormy weather.

Such things happen in Tokelau. Some-times boats are blown off course; there's even a Tokelauan word for this: lelea. It's theorized that the very existence of people on the island—it has been inhabited for a thousand years—is because a Polynesian canoe drifted off course. But there is also another, more complicated Tokelauan word: tagavaka. This applies to boats that have purposely sailed away—for love, adventure, or suicide. These days, Tokelauans commit suicide by driving into the open ocean until the gas runs out.

The following morning—no one, says the ulu, slept that night—help was requested from the Royal New Zealand Air Force. It swiftly sent out a P-3 Orion military surveillance plane with radar capable of detecting something as tiny as a submarine periscope. The total search area, according to Nick Olney, the Orion's wing commander, was more than 8,500 square miles. The plane searched three separate times—returning once to Samoa to refuel—for a total of eight hours.

Visibility was reasonable, says Olney, but there was sun glint on the waves. "Lots of noise," as he calls it. "I don't know how we missed them," he says, though he adds that boats so small, without a GPS beacon, are found only 20 percent of the time, even with the most sophisticated equipment.

A few hours after the search plane left, Samu began suffering from a rash, a bad one, a spray of itchy red bumps across his legs and arms, probably from sleeping for a couple of nights in a puddle of seawater. He scratched himself constantly, and soon there were flakes of skin all over the boat. Still, he hardly complained; Samu has a serious and quiet mien, an admirable quality among Tokelauans. He often answered my questions with just a raise of his eyebrows, an all-purpose expression that means "yes" or "I agree" or "that's funny" or "hmm" or a dozen other things.

At this point—approaching the third night, with no idea where they were, their supplies pitifully meager—you might think that panic would have set in, but when I spoke with the boys they all insisted no. They were sure someone would soon rescue them. On the next day, they finished the mayonnaise container of water and continued drinking the coconuts, this time making sure to scrape the insides. By that evening, they had used up all the gas. They could now only drift with the current. They threw all the fuel containers overboard. When they went to sleep, they had exactly eleven coconuts left.

Again, their sleep was fitful and wet. The wind picked up. Etueni, who'd lost his shirt the first night, was especially cold. In the morning, there was still nothing but water all around them. No rescue boat. No airplane. Etueni finally said it: "Shouldn't we be found by now?" The response from the others? "They laughed at me," Etueni says.

Their mouths soon grew very dry—despite storm forecasts, it had not rained at all during the trip—and the only edible items were coconuts. That day, they each drank and ate two, an extravagant use of their supplies, yet it wasn't nearly enough to slake their thirst or satiate their hunger. By the time they went to sleep that night, they had precisely five coconuts left.

At sunrise on the fifth day—the day the teens who had previously stolen a boat had been rescued—the boys all finally admitted, aloud, that they'd like to go back, that they wished they were home. "We started getting worried," says Filo. They agreed to eat only one coconut that day, split three ways. But one-third of a coconut was not nearly enough. "Our lips were still dry," says Etueni. "Our stomachs were hungry," says Filo. Still, they refrained from eating any more. "I was thinking about chicken," says Etueni. "Chicken, mayonnaise, and rice. The kind my mother makes." Filo, the city kid, imagined unwrapping a McDonald's double cheeseburger. Samu, who had never seen a McDonald's, talked about tuna stew. They all dreamed about pies. "And cakes," Filo says. "Chocolate cakes."

By the next morning—day six—the three were well aware that they'd made a terrible mistake. But what could they do? They sat on the benches, facing each other. They had no watch. Nothing to read. No pen or paper. They tried to distract themselves with conversation, but they had little to say. "It started to get quiet," says Etueni. "All I was thinking about was water and juice."

Soon they were down to their last coconut. Samu was in charge of cracking it. He used the machete, careful not to spill any of the precious milk. Samu sipped first. He passed it to Filo, who passed it to Etueni, who passed it back to Samu, who finished it. They scraped out every morsel of meat. And that was it. They threw the shell overboard.

They had nothing left.

There was just the sun, beating down on them. Thirst was like a hand around their throats. "That's when we started thinking about drinking seawater," says Etueni. Filo warned them that this was a bad idea; he'd learned it from a Discovery Channel show called I Shouldn't Be Alive. Seawater is three times as salty as the body's blood. In an effort to dilute this salt, water leaks from every cell in your body. For each ounce of seawater taken in, the body creates about one and three-quarters ounces of urine to wash it out.

The next morning, Samu—the lifelong Tokelauan—announced, "I'm drinking it," and dipped the teacup into the ocean. He starting sipping. "Then I got sick of looking at Samu drinking it," says Etueni.

"Me, too," says Filo.

They all drank seawater together.

How did it taste? "Yuck," says Etueni. But they kept drinking. It still had not rained.

They descended into silence. Hours passed between words. "We got sick of looking at each other," says Etueni. "We got sick of looking at the ocean. We got sick of looking at the boat."

And what would someone say when the silence was finally broken?

"I'm hungry," says Etueni.

Finally, more than a week into the trip, it rained. Hard. For ten minutes. And for the first time, the boys used the green tarpaulin, which had been balled up and shoved into the small hold in the bow. They took it out and spread it open in order to catch rainwater.

And at last something good happened.

There, hidden beneath the tarp, were three more coconuts. They were quite old—they'd probably been in the boat when they took it—and were cracked, all the water gone, and had been drenched by gasoline. But there was still some meat in there. They ate it all immediately and drank every drop of the rainwater they collected.

And then there was truly nothing left.

There have been, over the centuries, several incredible stories of survival at sea. Most recently, in August of 2006, three Mexican fishermen were picked up in a fiberglass boat after an astounding 285-day drift across the Pacific—an all-time record, in terms of days, by quite a margin. I researched dozens of these survival tales. And the more I read, the more I realized that almost no one experienced a harder trip than the Tokelauans. Perhaps only the survivors of the whaleship Essex had it worse. In 1820 twenty men abandoned the Essex, which had been rammed by a whale, and sailed for three months. They resorted to cannibalism. Only eight survived.

The key to staying alive, as evidenced by nearly every tale, is the ability to fish. The record-setting Mexicans had an array of jerry-rigged fishing gear, along with piles of warm clothing and containers capable of holding fifty gallons of rainwater. They caught hundreds of fish. They barely lost weight.

Poon Lim, the record holder before the Mexicans, was a Chinese castaway from a British merchant ship torpedoed in the Atlantic in 1942. He fashioned a small fishing hook from a flashlight wire and a larger one from a bent nail and proceeded to catch enough fish that he was able to walk off his lifeboat unaided after 133 days. Maurice and Maralyn Bailey drifted for 118 days in 1973 but had piles of canned food (braised steak, spaghetti bolognese) as well as a stove, books, and a deck of cards. They caught dozens of fish and turtles. Steven Callahan, who in 1982 survived seventy-six days, had two solar stills to convert seawater to freshwater and a speargun with which he caught several enormous dorados. Seven years later, Bill and Simonne Butler drifted for sixty-six days but had fishing gear, a set of dominoes, canned food, blankets, a radio, and seven bottles of Evian. They once tossed fifty pounds of fish overboard because they didn't like the taste.

Samu, Filo, and Etueni saw plenty of fish. The shadow of the drifting dinghy created a kind of artificial reef that attracted many small fish, which in turn enticed larger ones. There were also the ever-circling birds, who'd dive for fish during the day and sleep bobbing on the water at night. All the food the boys needed was visible to them, yet just out of reach.

Filo and Etueni imagined a solution. They wanted to break apart the engine and pull out a wire, or perhaps the thin coil on a spark plug, and form a hook. Catching something would have been relatively easy for Samu, who on Atafu was in line to become a tautai, or expert fisherman, the highest honor a Tokelauan man can receive. He already had scars on his palms, sometimes called "Tokelau tattoos," from hauling in fishing line hand over hand.

So even now—more than a week into the voyage, the situation quickly turning desperate—there was no question who had the final say about the boat: Samu. It was his uncle's boat, his uncle's motor, and he adamantly refused to allow anyone to touch it. This greatly frustrated Filo and Etueni, but Samu never budged. His opinion was clear: He would sooner die—and have Filo and Etueni die as well—before permitting anyone to rip apart a perfectly good engine.

I found this position hard to believe, and I shared in Filo and Etueni's frustrations, but when I spoke with other Tokelauans about Samu's stubbornness, everyone said that he or she completely understood. It's something Tokelauan, something deeply ingrained: You can steal another man's boat, but don't mess with his engine. The replacement value was more than $2,500.

For a while, Etueni tried fishing with his hand, just holding it in the water over the side of the boat. He says he actually felt fish but could never grab them. The boys also saw several sharks—a handful of whites and a hammerhead. One got very close, and Samu decided he could leap from the boat, machete in his mouth, and land atop it, then slice its throat. Only Samu would come up with an idea like that. The others pleaded for him not to try it, and the shark swam away with Samu still in the boat.

Through sheer happenstance, the boys did actually catch a few fish. The chief disadvantage of the low-sided boat was that seawater continuously splashed in. A wave of any size would break over the gunwales. Bailing during the day, using the mayonnaise jar, was constant, and at night the boat slowly filled up. But every so often—a total of four times during the trip—the waves carried along a fish that would flop into the boat. Three of the fish were tiny; Etueni described them as pinkie-sized. The boys would each have one bite. It tasted horrible—"It was yuck," in Etueni's parlance. They had no saliva, and it took all day for the bitter taste to dissipate.

One time, they got a bit luckier. A wave deposited a larger fish in the boat—probably a halfbeak, though the boys called it a "baby swordfish." The fish was dead; it had been floating on the surface. It came in the night. It was about six inches long. They ate it, four bites each. Etueni says he swallowed the entire head.

Once the boys finished their last coconut, that was their total food intake: three minnows and the baby swordfish—a total of seven bites—over the course of about a month. (Exact time periods were impossible to pin down, so the boys organized the story by events: "after the first rain," "before the last coconut," "the day of the swordfish.")

When it did rain, which happened roughly every other day, they'd form the tarp into a bowl. Flakes of skin would float about the rainwater, along with bits of plastic from the disintegrating tarp. At first the boys took turns scooping water with the teacup. Then one day Samu accidently hit the cup against the side of the boat, and it shattered. They started lapping at the tarp like dogs. They wanted to save some water but never could. Thirst was too overpowering. But at least, after a decent rainstorm, they say they felt almost full.

All of their skin soon grew torturously itchy rashes. The boys have dark, latte-colored skin, but the sun still overwhelmed them, igniting severe burns. The only way they could stay comfortable was to pull off their clothes. They threw them in the sea in anger and frustration. They kept only one T-shirt, Filo's, which they used to dry the bottom of the boat after bailing it.

Eventually, to avoid lying in the puddle, they started sleeping sitting up between the benches, legs and feet intertwined. They'd huddle together, wrapped in the tarp, while waves filled the boat. At night they didn't bother to bail. "We didn't care," says Etueni. "We just tried to sleep to get past that day." They napped in the daytime, too. Anything to kill time.

About two weeks in, they began bickering. By this point, the boys were starving. "It's like your stomach is being ripped apart," says Etueni. Of course they weren't in good moods. "We got angry easily," says Etueni. It was worst at night, when they fought for a little extra room. "Scoot over," "Move your elbow"—that sort of thing.

They had nothing to divert themselves. They lost track of how many days they'd been gone. The disc of the sun slowly traveled overhead. The water changed color—blue, green, gray, black—with fading light, with passing clouds. In rough weather they rode the great ocean swells, rising and falling sometimes thirty feet or more as if the sea were breathing. The horizon was naked save for the incessant waves that formed a swaying divide between ocean and sky.

"When it was night, I wanted it to be sunny," says Etueni. "When it was day, I wanted it to be night." Sometimes, in the darkness, specks of light from phosphorescent plankton danced below, its illumination triggered by the splash of waves. The gold ring that Samu wore, a cherished possession, slipped off his finger while he was scooping a palmful of seawater. He had grown skinny.

How long, they wondered, could they drift? They thought they'd surely spot an island. But the answer is that they could, in fact, drift a long while. It's possible to get caught in an enormous eddy system and circle for years. One ship, the Marlborough, left New Zealand in 1890 and then was purportedly seen again, off the coast of Chile, twenty-three years later, complete with skeletons of the crew.

Sometimes the boys prayed. It was all they could do. This was usually in the evening, as the sun set on another day adrift. They'd take turns. "God," they'd say, according to Etueni, "please take us back home. Please forgive us. We will be good." They made promises to God. "We'll never drink again." "We'll never smoke again." "We'll do well in school." "We'll be good boys." "We'll look after our families."

Sometimes they wept. They all did. "Tears just came," says Etueni. Someone would turn his back and cover his face, but the others knew. So they'd sit next to him, put their arms around him. They'd comfort each other in the best way they could. "It's all right, it's all right." "We'll get there." "We're gonna see your family again."

A storm blew in. It rained for two and a half days, the only major storm the boys encountered. They couldn't bail fast enough; water rose to the benches. They shivered violently—rain, even in the tropics, comes in cold—so they wrapped themselves under the tarp, sitting cross-legged. From outside the boat, they would have looked like a small green haystack. It was warm in there, so despite the boat filling up and in danger of sinking, they sat for an entire day, huddled naked, rain hammering down, thrashed by winds. They say they felt like a team at this moment, dependent on one another, helping one another, just the three of them in a tiny boat amid an endless sea.

A few nights later, they spotted a ship. It was a large one, the deck outlined in orange lights. They hadn't seen a boat since leaving Tokelau. It was difficult to tell how far away it was. They thought, Let's make a sail and catch up. So they held up the tarpaulin and tried to harness the wind. But it was exhausting work. So they debated whether to jump in the water and swim for it. Should only Samu go? Should they all go? They couldn't decide. And the boat motored away.

They felt terrible. They wondered if that was their only chance, if they'd die before seeing another ship. They thought about all the food on that boat. The warmth. The beds. They blamed one another for not jumping in the water and at least making an active attempt at saving their lives. Now all they could do was sit in their dinghy and wait.

Soon after the ship passed, Etueni quit. He stopped talking. He curled up in the bow. He didn't even sit up—he just lay all day in the bottom of the boat, mute. Mostly unmoving. Eyes half-lidded. He did this for weeks.

Starvation is an insidious process. After the body consumes all the food in your stomach and small intestine—a point the boys had passed weeks before—the energy stored in fat comes next. When all available fat has been consumed, your body turns on muscle tissue. You're basically being eaten alive, from the inside. The nagging in your stomach, your body crying for nourishment, is constant and unstoppable. Physical strength is sapped. It's difficult to think clearly. Everything seems to happen in slow motion. The boys developed, in all their fingernails and toenails, a noted sign of deep starvation, a ragged white square in the middle of each nail. Their hair started to fall out.

Etueni's breakdown infuriated Samu. Filo was neutral about it, but Samu understood that if they wanted to survive, they needed to work together. "Etueni didn't help us clean, didn't help bail, didn't talk," says Filo. "I'd say, 'How are you?' and he wouldn't say anything. He'd just lay there."

Etueni was locked in his own world. His tongue refused to work. "I wanted to talk," he says. "But I had a horrible taste in my mouth. Seawater didn't help. Nothing helped. I couldn't get rid of it, no matter what I did."

Phrases repeated in his head, over and over, for hours. "Why did I come? Why did I come?" "I hate this, I hate this." Then he contemplated dying, something no 14-year-old should have to do. "I thought about suicide," he says. He considered stabbing himself with the machete. But it had grown rusty and dull.

"I thought about the fastest way to die—the easiest, the least pain," he says. He finally arrived at a plan. He'd tie the cord from the engine around his leg, detach the engine from the boat, and jump over the side. "I didn't tell the others this," he says. "I just kept it to myself." They were probably floating over 10,000 feet of water.

Back in Atafu, as the weeks passed and there was no sign of the boys, people weren't sure what to do. At the school, they left the boys' desks empty. The fishermen never really stopped searching. They'd glance extra long at the horizon. Every morning people walked the beach, looking for a sign.

Filo's father, Tanu Filo, says he had frequent dreams about his son in which he could see Filo but couldn't talk to him. His mind told him there was no hope, but his dreams said otherwise. He felt helpless. He stopped working, went to the beach, and put up a tent. He stayed there many nights, staring out to sea.

The ulu was in a difficult position. He wanted closure but couldn't prematurely declare the boys dead. He was related to all three. "We had special services for them, morning and evening," he says. "But no memorial service. The only time we have memorial services is when death is confirmed. We can wait years." He says he never gave up hope. "I don't know why," he says. "We are taught to respect the ocean. Not fight against it. Go with the current." He spoke with a skilled boat captain in American Samoa who had closely followed the weather and the winds from the day the boys went missing. After six weeks, the captain told the ulu, "Sorry, those boys are gone." No one, he said, could survive that long without food or water.

Deep in his silent stage, pondering suicide, Etueni was alone, confined to the bow of the boat. Filo and Samu slept at the rear. They had the tarp. Etueni couldn't even stretch out. "If I straightened my legs," he says, "they'd kick me and tell me to pull them back." Sometimes, he says, because he wasn't helping, Filo and Samu drank nearly all the rainwater. Samu slapped him a few times to try and snap him out of his silence.

And then, while Etueni was huddled in the front of the boat, Samu asked him for the machete. He wanted to scrape his skin, to ease the painful rashes. Etueni refused to move. He told me later he had no idea where the machete was. As it turned out, it was under him. This, for some reason—this of all things—made Samu snap. He kicked Etueni. "Get up, bum," he said. But Etueni just lay there.

In a flash, Samu yanked Etueni up, grabbed the machete, and pressed it to his neck. "I put my fingers around it," says Etueni. "I pushed back." Samu pressed the machete so hard it cut into Etueni's neck. There was blood. Later, Etueni showed me the scar. "I really thought Samu was going to kill me," he says. Filo was sleeping on the other side of the boat but woke to the commotion. Etueni finally said something. "Please," he whispered. "I don't want to die." And Etueni realized at this moment that it was the truth. He didn't want to die. He didn't want to tie himself to the motor. And he didn't want Samu to cut his throat. He says he thought at that moment of his mom, of not seeing her again if he died. The two boys—separated only by inches, Samu pushing the machete one way, Etueni pushing back—glared at each other.

"Let go," Samu said to Etueni. Etueni didn't let go. Then, abruptly, Samu dropped the machete. It clattered on the aluminum floor of the dinghy. "You're lucky this time," Samu said. And he turned his back on Etueni.

"I sat up quickly," says Etueni, "and grabbed it. Jump on him now, I was thinking. I was thinking of killing Samu." He told me it was the first time in his life he had ever truly wanted to kill another person. "I could've jumped on him. It was a good chance. His back was turned to me."

But something stopped him. When I spoke with Etueni and he was describing this moment, he quoted Martin Luther King to explain what had held him back. He told me he'd read King's line in one of his schoolbooks and that it had always stuck with him: "We must all learn to live together as brothers or we will all perish together as fools." He put down the machete.

One afternoon, a bird—one of the gray gulls that hung around the dinghy—landed on the boat. The boys were half comatose. They stared at the bird.

Samu spoke to it. "Where do you come from, bird?" he asked. "What's your name?" The boys actually laughed. They thought it was a sign. A sign from God. An angel. "Can you take us back home?" asked Samu.

The bird did not answer. "I'm speaking to you," Samu said. "Hey! Pay attention." The gull remained there for a long time. It cooed. Suddenly, Filo lunged for it. The bird easily flew away.

A few days later, another bird came. It was just after a big rainstorm, and there was water in the tarp. This time, Samu tried to catch it. He was stealthy. He crouched low and grabbed the bird by the neck. He twisted it. When Samu thought it was dead, he let go. It immediately started squawking. He twisted again. Then Samu plucked the feathers.

He cut the skin with his teeth. They ate a bite of raw meat, but even in their hunger, it was worse than yuck. So they dried the carcass in the sun. And it was good. Better than good: possibly lifesaving. They ate all the meat; there wasn't a lot. They ate the organs—the heart, the liver. They rummaged in the stomach for bits of fish. They crunched up the bones and ate all of them. "Afterwards," says Etueni, "we wanted more."

They drank the water in the tarp. The sea was so calm that waves didn't splash into the dinghy. Etueni ended his silence. "The bird finally helped," he says, "and I started talking." It was a good day. "We were friends again," says Etueni. "We were happy that day." But no more birds ever landed on the boat.

The relief provided by those few bites of meat did not last long. It only served to reawaken their hunger pangs, their long dormant stomachs gurgling with digestive juices. But there was nothing more. Soon they were hungrier than ever. The sun continued to beat down. The sea stretched all around, limitless and cruel.

At times, Samu and Filo spent a few minutes bobbing in the water to cool off, but Etueni felt too frail to leave the dinghy. During one of these dips, the boys found barnacles on the bottom of the boat. Samu was the first to eat them. They were better than not eating. They gave some to Etueni.

Then, during one swim, Filo let go of the boat, trying to snap off a barnacle. The current was strong, and he drifted away. He was too weak to catch up. But Samu held the dinghy in one hand, and swam with the other, tugging the boat. It was an incredible feat, considering his condition. He managed to swim fast enough to reach Filo. He grabbed his hand. He helped haul him into the boat. That was the last time anyone went swimming.
