Alone

Ten new participants are abandoned in the remote wilderness of Patagonia, Argentina, where they must find food and water, build shelters before the onset of winter and fend off predators, such as pumas and wild boar.

As they venture deeper into their surroundings, the nine remaining survivalists realize that this 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.

The remaining participants are forced to get creative due to a lack of food; one survivalist devises an ingenious method for getting protein, while another battles a wily predator.

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 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.

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. But one participant takes it too far, reaching the breaking point and risking organ failure.

Short of food, the remaining participants risk their lives to be victorious; only one survivalist will be able to endure the wilds of Patagonia to take home the $500,000 prize.
