Thus Brad Barron and a group of desperados find themselves under siege, inside a house in an isolated location in the depths of a forest. This marks the beginning of a long night of terror and violence, and when it finally comes to an end Brad has to confront and destroy the very origin of evil itself, thereby running the risk of being transformed into a returnee himself as well!
