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?

The cold weather has set in, making it ever more difficult for the participants to catch food; as hunger kicks in, desperation takes over.

As the end of the competition nears, the final participants battle against nature and themselves. One of them will take home the $250K prize.

The Reunion brings the entire cast together for the first time since they were dropped into the extreme and wild terrain of New Zealand's South Island (Aotearoa's Te Waipounamu), having to survive completely isolated from the world and each other, and stripped of modern possessions and comforts. Join Andreas, Chace, Jack, Jason, Krzysztof, Leanne, Mike, Rick, Suzan and Tamika as they compare their strategies and experiences for the very first time, reveal the toughest struggles they faced and are shown surprising, unseen footage.
