Alex is a disturbed young man bent on destruction, but madness ensues when his plans get interrupted by his step-sister and her four hot college roommates. Confined to their parent's house as a blizzard moves in, the six settle in for a long, boring night. However, Alex's odd behavior becomes more suspect when the power goes out and one of the girls 'accidentally' dies. He tries desperately to cover his tracks, but all the while, he hides an even darker deed, and in the end, only one will survive.
