Holy Terror (2002)

Possessed by a demon in life and forced to spend eternity doing the devil's bidding in death, a malevolent nun returns to life to torment a young couple and their terrified friends in director Massimiliano Cerchi's sacrilegious shocker. A young couple has just moved into their new rental home, and in order to properly break the place in they have invited over a small group of friends for an intimate housewarming party. Soon prompted to experiment with an Ouija board by their sinister landlord, the unassuming party goers inadvertently unleash the murderous spirit of a demonic nun whose evil is so powerful that it cannot be contained to the spiritual realm.
