Ten new participants return to the History Channel's #1 summer survival series. In Big River, Labrador, the participants face the stalking predator, the Polar bear.

As hunger rapidly sets in, the remaining participants rush to get familiar with the land and do whatever it takes to secure food; one survivalist thinks outside the box for dinner; one participant struggles and makes a costly mistake.

As Labrador's winter draws near, the participants split their time between building permanent shelters and getting food; many participants struggle; one allows an opportunity to slip through their fingers; one braces for a deadly encounter.

As they continue to settle into their new surroundings, the participants aim to procure food for the long haul; one survivalist risks hypothermia by entering the frigid Labrador waters while another realizes they bit off more than they can chew.

The participants continue to look for new ways to hunt, but also to preserve their food sources; one survivalist leans heavily on a taxing shelter build, while another pauses their own work for some much needed sustenance.

As the participants close in on the first thirty days, the lack of food and the desire to go home grows ever stronger in Labrador the competitors continue to make each opportunity for food count; the need for preservation has one getting creative.

The survivalists get serious about hunting before the wildlife starts to disappear for the winter; One participant has a chance to make history by taking down big game, while another is set back by a nasty puncture wound.

As temperatures drop to the lowest point yet, the lake freezes, cutting off resources and threatening the safety of the survivalists. Each participant's grit and resourcefulness is tested by the unrelenting cold, causing one survivalist to hit their breaking point much sooner than expected.

The final three survivalists continue to battle weight loss, extreme temperatures, and predators to remain in the fight for the $500,000 prize. The punishing cold makes getting food harder than ever before and a devastating catastrophe causes one participant to lose everything. The remaining survivalists push on, but in the end, only one is able to conquer the Arctic and emerge victorious.

With the competition in its final stage, only one survivalist's resolve can secure them the $500,000 prize. As the temperature dips well below freezing, the river stops paying dividends. The three participants are forced to weigh tapping out versus a lifetime of regret.

With only three survivalists left, the million-dollar challenge comes to an end. The participants face off against below zero temperatures, injury and their own mental demons as they fight to make it to day 100 and win the million-dollar prize.

After some of the participants are raided by predators, they scramble to protect their hard-won food. Winter moves in, bringing with it new opportunities for those who are prepared, and new threats for those who aren't.

As the participants march deeper into winter, it becomes increasingly difficult to procure food. One participant gets a lucky break, but soon discovers things aren't what they seem. Another attempts to do battle with his own mental demons while another's time in the Arctic comes to an explosive finish.

As the river finally begins to freeze, the remaining survivalists struggle with the loss of daylight. One participant's snare line gets stalked by a vicious predator, while another devises a plan to defeat a longstanding enemy.

Icy rocks and unpredictable waters force the remaining participants to decide if their desperate need for fat is worth taking dangerous risks. One participant is faced with a deadly predator threat and braces to fight for his life.

With only four people remaining, food insecurity reaches an all-time high. One participant's prized harvest is pilfered, while another survivalist battles a debilitating sickness brought on by an unfortunate source.

The final remaining participants face the onslaught of Mongolia’s brutal winter. Relentless hunger and savage cold test them like never before and in the end, only one will walk away with the $500,000 prize.

One survivalist rushes to prevent their shot at a million dollars from going up in smoke. Another struggles to complete their shelter in time for winter, while another must defend their territory from an unwelcome visitor.

In Alone's most remote location, ten new survivalists must survive north of the Arctic Circle as they face the cold and dwindling sun for a chance to win $500,000. While the participants prepare for frigid temperatures and dangerous predators, the Mackenzie River Delta begins to test each survivalist. With signs of grizzly bears and wolves all around, one survivalist learns the biggest danger could be himself.

Extreme isolation takes its toll on the remaining participants in the wild. Each man’s battle turns to the mind as well as the elements.

As they enter the second week of the competition, the participants focus on securing a food source that can last them 100 days. Many focus on fishing, another puts himself in a dangerous position to keep his food safe -- with disastrous consequences.

Faced with choppy waters and brazen predators, the participants must shift strategies or starve. One sets his sights on big game.

Local predators continue harassing the participants and they must adapt and innovate if they hope to survive. One is forced to make a hard decision when an unexpected catch turns up.

The Arctic's frozen landscape continues to push the remaining survivalists to the brink. One participant finds themselves at-risk for frostbite, while another is convinced the end days are near.

As food sources disappear, hunger drives the remaining participants to a new low; one attempts a risky climb into wolf territory in search of food and another contends with a potentially game-ending health issue.
