Watch Night of the Demons

During a Halloween party a group of ten friends end up bringing a demon back from beyond, and suffer the consequences at an abandoned mortuary. Two friends, Angela and Suzanne decide to throw a party at a deserted mortuary that was abandoned after the family who lived there were murdered by an unknown assailant. The plan is to scare all the invited guests. The usual cast of characters, jock, outcast, preppy and tough guy, are all invited, and on their way to a store for supplies they harass an old man who seems harmless, but is hiding a dark side, and he cusses them out even as one of the girls tries to help him with his bags which show his plan to put razor blades in apples to give out on Halloween. As the first group arrives at the mortuary, they encounter a wall surrounding the property, and Jay tells them it marks an underground stream and that spirits can't cross running water. They all go inside to see they are the first to arrive, and find a coffin in the front entry. Jay decides to climb in and scare the next guests who are just pulling up to the house, but when he opens it, Sal, another guest, is already inside and leaps out to scare Jay. They argue, then more guests arrive. The party is in full swing when the batteries in the radio die out, and then it is suggested that they have a seance as a party game. The seance has opened the doorway to unleash a demon, who possesses Suzanne. Two people try to leave, but are killed since they could not find the gate in the wall around the property. Four go off, to explore the house, and as they are leaving, Suzanne kisses Angela, passing the demon to her. She then goes with Jay, Stooge and Judy. The four find a room, and Stooge tells the story of what happened in the house, and the demon who still lives there. Jay makes Stooge and Suzanne leave, hoping for some time alone with Judy, so they leave to find a bathroom. Suzanne goes in, looks in the mirror and sees herself age and turn into a demon. Outside the door, Stooge hears what sounds like a mirror breaking and goes in to find the room empty. Jay and Judy argue, and he leaves the room, which locks behind him trapping Judy. Once she manages to escape the room, the two are then pitted against their possessed friends, and have to find a way out of the house to save themselves. They go out the window when cornered and have to climb the wall since the gate is gone. Jay goes first, seeming to leave Judy on her own, and the demons are after them. He reappears and helps pull her over the top as the sun is coming up and destroying the demons. They walk away, beat up and tired, and pass a small house on their way back to town. Inside the house is the old man, and his wife, and he is eating some homemade apple pie she made for him. He does not know it but she used the apples he had planned to hand out, and the razor blades are cutting inside his mouth and throat, killing him. His wife pats him on the head and says Happy Halloween as she is having her coffee.
