Ten outdoor survivalists are challenged with surviving totally alone for as long as they can in Tasmania's wilderness in the middle of winter.

The contestants start to tap out of the competition, as they find out how tough a Tasmanian winter can be and the conditions prove too tough for some.

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.

The participants reveal the sources of their strength as they contend with hunger, the elements, and their own thoughts in the Tasmanian wilderness.

The participants struggle with hunger, fatigue, cold, and the question of whether this challenge is worth it.

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.

The remaining competitors in the Tasmanian wilderness have no idea how much longer the competition will go on for, heightening the daily challenges.

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.
