The adventure begins as ten new participants are abandoned in the remote wilderness of Patagonia to live as long as they possibly can. Faced with the unforgiving terrain of a foreign land and the onset of winter, each must act quickly to adapt to their new environment in order to survive.

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.

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.

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 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.

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.

While most of the participants pursue smaller, more consistent food sources, one survivalist finally has the chance to take down big game; he soon finds himself attracting unwanted attention from predators.

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.

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 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.

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.

As they approach the one month mark, the participants' survival is threatened by new factors. One contestant is forced to defend themselves from a huge predator. Another risks losing their shelter in a horrible accident. And another struggles with the most challenging element of them all: being totally alone.

Participants begin successfully procuring food but still find themselves vulnerable to the Arctic's many dangers. A sudden illness attacks one participant, while another is tormented by a tiny invader.

With only 3 left in the competition, the participants struggle to claim the $500,000 prize. While some continue to deal with the mental game, a new predator threatens a survivalist's longevity.

The three remaining survivalists brace themselves for the fight to the finish. One participant finds it impossible to stay warm, while others risk it all on the ice. Though they all push themselves to their limits, only one can claim the $500,000 prize.

In a new twist, seven family member pairs are dropped miles apart on Northern Vancouver Island and must find each other. To win the $500,000 prize, they must survive the island's unforgiving terrain and deadly predators together.
