Several satanic clones of Mandeville, Coyle and the other scientists enter the house, and begin killing off the originals and taking their place. When Coyle is about to be killed, she is rescued by the poltergeist and saved. The satanic monks then take off in a spaceship, revealing that these monks are aliens using the house for their activities on Earth. The film ends with the spaceship soaring into the skies, with the familiar voice of E.T. groaning: "Oh, shit! Not again!".
