Ten new participants confront the most grueling challenge in Alone history: last 100 days in the Arctic in order to win $1,000,000. Facing a variety of predators is the first hurdle they must overcome.
Faced with the arduous task of lasting 100 days, the participants get to work building shelters that can endure the harsh Arctic winter. Others begin securing food, making them the unwilling target of dangerous predators.
As they enter the second week of the competition, the participants focus on fishing to provide a long term food source. One participant experiences a frightening accident, while another comes face-to-face with a million dollar meal ticket.
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.
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.
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.
