Plot summary

On Halloween night, a group of 10 teenagers led by Angela (Mimi Kinkade) and Suzanne (Linnea Quigley) decide to have a party at Hull House, an abandoned funeral home. The house was the scene of a horrifying murder-suicide committed by the owner's son some years before, and had spawned legends of 'the boogeyman' among local children, who avoid it. It is also rumored to have been built on unholy ground, according to local Indian tribes, and a high wall was erected over an underground stream on the property to keep the evil spirits confined, as they cannot cross water. The teens soon start engaging in a party inside the house, with dancing and alcohol. But it isn't until Angela conducts a seance that trouble starts brewing. The face of a demon appears in the mirror and vanishes quickly, but not before one of the girls sees it. In the mansion's depths, the demon seen in the mirror pushes open a heavy steel door and closes in on the teens. The demon takes control of Suzanne first, and then, one at a time, the other teens become possessed or are murdered savagely, only to come back to life as demons. Eventually, only 2 of the teens - Judy (Cathy Podewell) and Rodger (Alvin Alexis) - are left alive. Will they escape the 'Night of the Demons', or fall prey to the horrifying demons that their friends have become?—Derek O'Cain
