Brainscan (1994)

Horror films and computer games fascinate teenager Michael (Edward Furlong), and a CD-ROM that portrays murder from the killer's point of view combines these interests. The first time Michael plays it, he kills a stranger and cuts off a foot, thinking the events take place in virtual reality. But the next day Michael finds a foot in his refrigerator, and cyber-ghoul Trickster (T. Ryder Smith) emerges from the program and forces him to keep playing -- and to continue committing violent crimes.
