Ten participants must face the unforgiving terrain in the remote wilderness of Patagonia, where they must learn to adapt quickly before the onset of winter.

As the participants venture deeper into the unfamiliar terrain, they realise the depth of their situation; one survivalist suffers a serious injury.

Driven by a lack of food, participants are forced to get creative. While one participant devises a method to get protein, another battles a wily predator.

Participants from season three reunite to discuss their experiences and creations, and to reveal never-before-seen footage.

As winter approaches, the contestants have to deal with the deteriorating conditions. The remaining survivors experience intense bouts of homesickness, and a lack of protein pushes new levels of depletion.

The survivors must turn to land game as the winter season approaches. However, their prey turns out to be more deadly and clever than they thought.
