On a rainy night, six priests, led by Father Manfred, enter the infamous
Amityville, New York house and start to exorcise it. One of the priests, Father Dennis Kibbler, is in an upstairs bedroom and begins to bless it when he sees a glowing brass
floor lamp. 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 rendered unconscious. A few days later, a real estate agency decides to have a yard sale by selling the previous owners' items left in the house. Father Manfred believes that the evil spirits are finally gone from the house. Meanwhile, at the yard sale, a woman named Helen Royce and her friend Rhona are looking through the items when Helen finds the lamp. At only $100.00, Helen decides to buy the lamp as a birthday present for her sister Alice Leacock, explaining that she and Alice send each other rather ugly gifts as a long-running joke. While checking the lamp, Helen cuts her finger on a brass collar around the bulb. Ignoring the cut on her finger, Helen buys the lamp. Helen's finger begins to get infected and discolored as the day goes on. Helen later dies of
Tetanus. One week later, the lamp arrives at Alice's house, a large, three-story home over a beach in a small town called Dancott, California. That day, Alice's daughter, Nancy Evans, and her three children, Amanda, Brian, and the youngest child, quiet, mysterious Jessica, move in with Alice. Once they arrive, Alice decides to open the package containing the lamp. Nancy thinks the lamp is hideous, while Alice finds it interesting. Once the lamp is turned on, Alice's parrot, Fred, begins to act crazy, and her cat, Pepper, scratches Amanda. While the rest of the family pays little to no attention to the lamp, Jessica seems to be drawn toward it. The lamp then begins to manipulate electrical devices around the house or perform seemingly impossible feats, such as killing the parrot and putting it in the toaster oven, turning on the kitchen sink's garbage disposal, and cutting off the hand of Danny, the son and apprentice of electrician Reade, and vandalizing Jessica's room. When Nancy calls Jake, a plumber, to fix the pipes, the lamp murders him by drowning him in sewage and then makes his van leave on its own, making it seem like he left. Jessica is drawn to the lamp and starts to believe her dead father Frank's spirit is inside it. Meanwhile, Father Kibbler, while staying at Father Manfred's place, gets a call from the lamp, which makes smoke come out of the phone and melts the speaker. Worried, he travels to Dancott to investigate. When most of the family is away, Jessica is entranced by the lamp, which then uses its extension cord to murder their housekeeper Peggy. The police investigate though they do not find Jake's body. Father Kibbler contacts Nancy and tries to convince her that the evil has taken possession of an object from the Amityville house. They rush home only to find that the lamp used a window to knock out Amanda and has brainwashed Jessica, who stabs Father Kibbler in the shoulder while the lamp's extension cord tries to stop him from exorcising it. Alice saves the day by grabbing the lamp and throwing it out of the window, shattering it on the rocky shoreline below. The movie ends with the family thinking their ordeal is over, not realizing that Jake's body is still inside their house. The camera pans to the remains of the lamp, showing the evil within has now possessed the family's cat Pepper. ==Cast==
