Ten new participants last 100 days in the Arctic to win $1 million, and they must overcome the first hurdle,which includes facing a variety of predators.

In order to endure the Arctic for 100 days, the participants start building shelters that can make it for the long haul, turning their attention to procuring food and inadvertently drawing the attention of dangerous predators.

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.

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.

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

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.

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.

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.

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.

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.

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.
