The tale of a CD ROM game that gives new definition to the term "interactive" is the subject of this horror movie, notable for its lack of the blood and guts that have characterized modern horror films. 16-year old Michael loves horror movies. The lonely, misanthropic nerd also loves computers. His mother is dead, and his father is frequently away on business so Michael has a lot of time to kill. While reading a horror magazine Michael spies an ad for Brainscan, an interactive CD-ROM. The game is designed to "interface with your unconscious." Intrigued, Michael buys it. Trouble ensues the first time he plays after he is hypnotized by the screen and dreams of stabbing a stranger and then amputating his foot. The shaken boy awakens only to discover a human foot in his refrigerator. He soon meets the evil rocker Trickster who lives within the CD. Trickster warns him that the police will soon discover what Michael did. To save himself, the boy must follow Trickster's rules. The first is that he must keep playing new versions of Brainscan.
