Whilst hunting in the snowy wilderness, Billy takes refuge in a seemingly abandoned log cabin when he suffers a shotgun wound to the leg.
Inside, kind and kooky lone inhabitant, old lady Agnes, is keen to nurse Billy back to health. But Billy soon learns this is no ordinary cabin, for he and Agnes are stalked by bloodthirsty skinless creatures that lurk in the surrounding forest, leaving them trapped together inside the cabin in a fight to stay alive.
