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.

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

While Johnny, Sam, and Daniel explore the research station, trying to restore the power, they make several grisly discoveries. Meanwhile, at the settlement one of the missing contestants resurfaces and warns Sabina and Neeko that "they" are coming... and they're neither animal nor human.
