As part of a reality game, sixteen contestants descend on Siberia, near Tunguska. They take up residence in a settlement where the people mysteriously disappeared without a trace over a hundred years ago. At first the contestants compete against each other for the chance to win $500,000. However, they soon discover that they are fighting for their lives when the sky fills with green flame, mysterious creatures stalk the woods, and the production camp is wiped out. When a mysterious snowstorm strikes in summer, the contestants must try and make their way to safety with little more than the clothing on their backs.
The contestants are reunited at the research center and wait for rescue, but the people that come for them prove less than friendly. After a daring escape, the contestants make it to the nearby town, only to face a betrayal from within and a surprise ending.
