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.

With difficulties of acquiring food, some find it challenging to trust their own judgement, while others start to feel the true effects of isolation.

Torrential rain batters New Zealand's South Island, with contestants facing danger if they brave the elements to hunt or starvation if they don't.

New Zealand's wild weather, lack of food and some bad luck force all of the contestants to dig deep in order to survive.

Frustration reaches a tipping point for most of the contestants, as finding food proves difficult for some and a severe storm rolls in over the horizon.

A dangerous storm hits, testing the contestants' resilience and shelters. Who will weather the rain, and who will struggle to adapt?
