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.

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.

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, and the pull to see family is more than some can bear.

As winter draws nearer, and fish stop biting, 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 could imagine.

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

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.
