The movie begins on a rainy night. We see the infamous The Amityville Horror house. Six priests, led by Father Manfred (Norman Lloyd (actor)) enter the house and start to exorcise it. One of the priests, Father Dennis Kibbler (Fredric Lehne) is in an upstairs bedroom and begins to bless it when he sees a glowing brass Light fixture. As he begins to chant, a burst of energy emerges from the outlet, through the cord and into the lamp. A demonic face appears in the large round bulb. Kibbler is knocked across the room and is unconscious.
