Founded in Hamburg in the 1970s, the gay theater "Brühwarm" toured Germany with its musical cabaret. Founding member Corny Littmann wrote the lyrics and Rio Reiser ("Ton Steine Scherben") provided the music. The result was a new form of theater as a political tool. In the documentary, former members of the theater have their say and give an impressive account of how the theater group, with its emancipatory and political aspirations, fought for gay rights in the turbulent political times of the 1970s.
