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.
