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.

As they venture deeper into the wilderness, the nine remaining survivalists realize the terrain is unlike anything they've ever experienced; one participant suffers a serious injury.

The remaining participants dig in for the long haul as they begin building their shelters. While some flourish, others fail and one is threatened by an unwanted visitor in the night.

A lack of food forces the remaining participants to get creative.

The remaining participants struggle to adapt to life in Patagonia. One survivor comes face to face with a stealth cat, and another takes on a major build project. As the days go by, one participant tries a novel strategy to outlast everyone else.

Dangerous challenges wreak havoc on the participants and force most to consider going home. While one is plagued by a potentially life-threatening infection, another battles against serious hypothermia.

As winter draws near, the participants turn to land game to survive the season, but their intended prey turns out to be more clever and more deadly than they ever could have imagined.

Winter arrives in full force, and the remaining survivors must deal with rapidly deteriorating conditions; the lack of protein pushes some to new levels of depletion; others find the pull to see family more than they can bear.

The remaining survivalists push themselves to their physical limits as fish becomes scarce; one participant takes things too far, reaching the breaking point and risking organ failure.

The remaining participants, short on food, risk death in their attempt to triumph. Only one survivalist will be able to endure the wilds of Patagonia and take home the $500,000 prize
