The Video Dead (1987)

The writer Henry Jordan receives a mysterious TV set and soon he learns that the apparatus is a gateway through which undead come to the world of the living. They kill Henry and the house is sold to another family. The teenager Zoe Blair comes to house to clean it for her parents that are traveling abroad. Her brother Jeff Blair comes later to help Zoe and finds the TV set in the basement. He brings to his room and out of the blue, the stranger Joshua Daniels knocks on the door. Joshua explains that he sent a TV set mistakenly to that address, instead of to the Department of Occult Warfare. Jeff does not believe in Joshua, but soon he leans the truth about the TV of the undead.
