Three days into the competition in the Tasmanian wilderness, three participants have already left, and the rest are feeling the effects of going without food.
After making it through the settling-in period, the remaining participants figure out their own strategies, which they hope will allow them to outstay their competitors.
The contestants approach two weeks in the wilderness and, with most of them not having caught anything to eat, food is becoming a critical issue and desperation is growing.
Survival in the wilderness proves to be just one part of the challenge. Emotional isolation weighs heavily on the participants, and the toll is too great for one person.
After ten days in the Tasmanian wilderness, just five participants remain. Having survived the settling-in period, each contestant focuses on their own strategies.
The worsening weather poses a tough challenge for the contestants. As it becomes apparent that a change of strategy is significant to their survival and success, they are forced to make some tough choices.
Ten survivalists take on the wilderness of New Zealand's South Island, documenting their own isolated battles and striving to be the last person standing to win $250,000.
The contestants try to adapt to the extreme conditions on the South Island of New Zealand, where they face near-zero temperatures, icy-cold winds, relentless rainfall and vicious sandflies.
The participants' focus turns to food. Some want to head up the mountains to hunt deer, while others opt for fish and berries. But with limited calories and tools, procuring food is no easy task, so they must think outside the box or risk starvation.
Frustration reaches a tipping point for most contestants, with varied methods of catching fish proving too much for some. On the horizon, a severe storm rolls in.
10 survivalists are dropped into the West Coast Ranges of Tasmania for the challenge of a lifetime: survive in the wild without any human contact. But only the last one standing can win $250,000.
A triumphant catch staves off the hunger of one survivalist, but as the adrenaline of the adventure fades, can the others pivot their strategies to bring in food?
One survivalist's body begins to shut down, another is forced to reckon with their emotions, and a wildlife encounter threatens another's chances at winning.
The remaining survivalists come face to face with their physical limitations. Can innovation save the day, or will a routine med check bring one survivalist to the end of their journey?
The survivalists' bodies are under more stress than ever before. As winter closes in, a swell of rain raises the lake's level, potentially putting shelters at risk.
Against all odds, our remaining survivalists have battled hunger, loneliness, flooding and extreme physical and mental challenges - but only one can win.
