TV Buster (1989)
A couple are watching television together. Over time, the shows become more bizarre: a news report about the arrest of two terrorists reveals they have the same faces as the two spectators; in another, a female strips for the man and finally a politician demonises the couple and declares them enemies of the people. Panicked, the couple phone a television exorcist.
