Mary Whitehouse played by the divine Julie Walters CBE could have been silly, over-reacting, or just a caricature of a woman who fought and won in her own mind. The film is quite a tribute to a woman who caused a lot of trouble in the 1960s regarding television content. Whitehouse is a schoolteacher, mother, and wife to Ernest. They live not in London but in Wolverhampton and she is concerned by the explosion of sexuality on television through the BBC which is national television. She gathers and recruits quite easily mostly housewives who have the same concern. All she wants is some time with the director of the BBC which was Sir Hugh Carleton Greene who is portrayed a chauvinistic boss and unlikely character. Whitehouse has her moments like when she telephones the BBC regarding a sketch spoofing her husband involved in a car accident as crossing the line. There is more to it. Despite all of the hatred and vulgarity in the letters and telephone calls, Whitehouse is persistent in trying to clean up the filth in national television.
