The story of two 12th century female gargoyles released in the 20th century.

Carl J. Sukenick is the commander of a branch of the CIA, battling terrorists with martial arts, while his dad keeps watch in the security center. Neal was sent out, but is a traitor, and he was mutated by a radiation blast. He sends Sara Shell to meet her husband, Agent Mark Shell, and daughter Sheila, but the three are brutally maimed and murdered by enemy agents. One cuts off Sara's hand for no apparent reason. A radiation blast from Neal the Traitor, who is wandering around an aqueduct killing passersby, mutates Joe as well. Carl says they knew nothing of the "hideous extra-dimensional being" breaking into this dimension, but he sends Evon, Rhonda, and Hackney to fight the mutations and the agent, who giggles constantly, before learning that there is another traitor and an alien, so he decides he must kill all his friends and find and kill the "hideous extra-dimensional being."

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.
