Sixteen international contestants are dropped by helicopter into an unpopulated Siberian wilderness. With only the clothes on their backs, they must try to survive with no help from producers or the outside world to win a big cash prize. They are soon faced with frightening events and unexpected situations that go horribly awry.

A shocking announcement comes with the loss of another contestant, while those who remain are dealing with deception and drama, including accusations of theft, the discovery of a bloody scene in the woods and arguments over food rationing. Elsewhere, Victoria suffers a frightening hallucination after being tricked by Esther into eating uncooked mushrooms.

The contestants grow suspicious of one another; Esther proves herself a strategic player; Carolina reveals a shocking truth; and a mysterious sighting in the woods causes fear and panic.

Johnny, Joyce and Daniel tell the others about the bloody scene they found at the abandoned producers' base camp; some of the contestants freak out over the prospect of having to fend for themselves in the wilderness; Esther is attacked verbally; Sam gains possible insight from Miljan's century-old Russian diary; and the appearance of a radio-tower beacon offers a glimmer of hope

In the season finale, a reunion of the contestants marks a possibility of hope and salvation; but the eventual arrival of the rescue party turns out to be the most dangerous encounter yet!
