This movie is known as a "flesh flick," a popular genre during this time, which explored sexuality and social norms.

Joe (Robin Askwith) hails from a provincial town and harbors dreams of fame and wealth in the thriving city of London. Together with his girlfriend, Carol (Janet Lynn), they make their naive, brave attempts to make a name in the glammed-up city.
