Continuing from ''The Rocky Horror Picture Show'' are the characters of Brad and Janet Majors (now portrayed by Cliff De Young and Jessica Harper, respectively), now married. The film takes place in the town of Denton, USA, which has been taken over by fast food magnate Farley Flavors (also De Young). The town of Denton is entirely encased within a television studio for the DTV (Denton Television) network. Residents are either stars and regulars on a show, cast and crew, or audience members. Brad and Janet, seated in the audience, are chosen to participate in the game show ''Marriage Maze'' by the kooky, supposedly blind host Bert Schnick (Barry Humphries). As a "prize", Brad is imprisoned on ''Dentonvale'', a soap opera that centers upon the local mental hospital run by brother and sister Cosmo and Nation McKinley (Richard O'Brien and Patricia Quinn).
