They only come when it snows, and nobody ever gets away. A group of close friends gathers at a secluded cabin in the wintry mountains of Colorado for a final holiday hurrah. Instead, it may be their last stand. First a massive blizzard leaves them marooned. Then the more chilling realization: something is lurking in the woods, watching them, waiting... Now a weekend of family, friends, and fun has turned into a test of love and loyalty in the face of inhuman horrors. The only hope for those huddled inside is to fight—tooth and nail, bullet and blade—for their lives. Otherwise, they'll end up like the monsters' other victims: bright pools of blood on glittering snow, screams lost in the vast mountains.
