John Ritter and Pam Dawber star as Roy and Helen Knable, a suburban American couple having marital problems. Roy has become a couch potato, and a resentful Helen wants him to ditch the remote. When the demonic Spike (Jeffrey Jones) offers Roy a deal on the ultimate satellite TV system, Roy doesn't realize that he's just signed away his soul. Roy and Helen are sucked into their own television, where they endure a gauntlet of Hellish television shows such as "Northern Overexposure" and "I Love Lucifer." When their kids Darryl (David Tom) and Diane (Heather McComb) realize that their parents are on the twisted television, they set out to rescue them.
