When he happens upon "Videodrome," a TV show dedicated to gratuitous torture and punishment, Max sees a potential hit and broadcasts the show on his channel. However, after his girlfriend auditions for the show and never returns, Max investigates the truth behind Videodrome and discovers that the graphic violence may not be as fake as he thought.

Social misfit Mahoney has been forced to sign up as the only alternative to a jail sentence and it doesn't take long before he falls foul of the boorish Lieutenant Harris. But before long, Mahoney realises that he is enjoying being a police cadet and decides he wants to stay... while Harris decides he wants Mahoney out!
