After six friends arrive at a mountain cabin for a long weekend, a monstrous snowstorm traps them. Soon the spirits of the Donner Party -- frontier settlers who resorted to cannibalism in a similar snowstorm -- begin to haunt them. As they start turning on each other, it's not clear whether the ghosts are real or the result of their fear. James Kyson Lee, George Stults, Tiffany and Penny Drake star in this tense psychological chiller.
