The American oil company KIC Corporation is building an ice road to explore remote Northern Alaska seeking energy independence. Independent environmentalists work together in a drilling base headed by the tough Ed Pollack (Ron Perlman). Upon returning to the base, he finds that his ex-love interest Abby is dating environmentalist James Hoffman.
When one insane team member is found dead naked on the snow with a camera nearby, Hoffman suspects that sour gases may have been accidentally released in the spot provoking hallucinations and insanity in the group. According to the camera, something quick and mysterious killed him. Despite the assumption of hallucinations, Hoffman begins to see ghost deer stampeding near the compound. After a plane scheduled to escort the team out crashes into the compound, Hoffman and Ed attempt to travel to a nearby station.
While Hoffman and Ed are away, the remaining 4 at the station begin to suffer under extreme pressures. The indian member of the group disappears with only his boots remaining. Another female member suffocates the injured and wounded technician, and Abby accidentally kills her by knocking her head against a sharp corner.
Hoffman and Ed discover that the help they are searching has disappeared, and before they know what to do next, they are both encountered by the Wendigo, a translucent beast that has been killing several of the crew. Both of them are killed. In the end, Abby awakens in an empty hospital, and after going outside, discovers that the sour gases that infected and killed most of her crew has now reached outside the compound.
