Poco Alan

A psycho kidnaps young men to keep them captive and use as his own personal sex slaves.

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.
