Mondo Rocco is a collection of short films weaved together as it was seen in the Park Theater in Los Angeles in 1969/1970. Charming in their innocence, Rocco's films captured important moments in gay history and are an invaluable resource.

The film, narrated by "LA Plays Itself" director Fred Halstead, begins by looking at the muscle magazines and films of the late 1940s-early 1960s, then at the softcore films of the late 60s and the boundary-pushing and legal-testing which allowed these to evolve into hardcore loops and then features.
