Shock Treatment is a 1981 American musical comedy film directed by Jim Sharman, and co-written by Sharman and Richard O'Brien. It is a follow-up to the 1975 film The Rocky Horror Picture Show. While not an outright sequel, the film does feature characters from the previous film, most portrayed by different actors, as well as several Rocky Horror actors in new roles. The film stars Jessica Harper as Janet and Cliff DeYoung in a dual role as Brad and the film's main antagonist Farley Flavors, with O'Brien and Patricia Quinn playing sibling character actors, Cosmo and Nation McKinley, and Nell Campbell playing Nurse Ansalong.

Plot

Continuing from The Rocky Horror Picture Show are the characters of Brad and Janet Majors, now married. The film takes place in the town of Denton, USA, which has been taken over by fast food magnate Farley Flavors. The film is set within a DTV (Denton Television) network television studio and opens as the studio audience is admitted into the studio. 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. While on the Marriage Maze, Brad is deemed "an emotional cripple," and is forcibly sent to Dentonvale, a mental hospital located in the studio run by siblings Cosmo and Nation McKinley and the subject of the synonymously named reality show, for "treatment."
