A group of friends here decides to experiment with the occult, which has for direct consequence the gradual degradation of the group. One of the group begins to show signs of obsession, and so with the rest of the staff decides to use the dubious instructions to perform an exorcism. But this is not a game for amateurs, so instead of solving the problems will trigger a much more powerful and pomstychtivějšího spirit, who wants all death. The only chance for survival is to uncover the deepest secrets of the house and find a way out before it's too late...
