Terrence Shade (Eric McCormack) takes his children on a holiday getaway to a cabin in the woods. But when a blizzard buries the house, the family finds themselves trapped and without communication. As the storm surges on outside, a sinister presence materializes. Unable to explain it, and unable to escape it, they quickly realize that maybe they haven't locked the evil out - instead they've just locked it in.
