Two couples vacationing in Alabama are pursued by a maniac killer. They flee deep into the woods and take refuge in an old house that has been vacated for years, or so they think. They soon discover that they are not alone and that the killer has purposely lured them to this house. It seems that the killer and the house are somehow working in concert. They try to leave, but the house won’t let them.

After receiving a message in which the killer claims to have killed God and now demands more dead bodies, the couples come to understand that the seeming malevolence of the house mirrors the evil within their own hearts and souls, and that they can only defeat the evil in the house by defeating the evil within themselves.
