Couch potato Roy Knable has entered a new dimension in TV viewing - on the other side of the screen. If he survives, he can return home. If not, like a show with no audience, he'll be cancelled ... for good. Don't touch that dial! Sit back and experience the hilarious misadventures of suburban couple John Ritter and Pam Dawber catapulted by their new satellite dish into an alternative TV dimension called Hellvision. Peter Hyams (End of Days) directs; Eugene Levy and Jeffrey Jones co-star.
