Sex seems to be the only remaining means of communication in an immense apartment building in a modern city suburb. At least that is the impression given by Blue Movie , which concerns the adventures of a virile young man. Michael is released from prison after five years to enter a society where complete sexual freedom flourishes. The rehabilitation officer helpfully places him in an apartment, but the love loves of his new neighbours do not stay hidden for long. An attractive neighbour is ready to help the sex-starved Michael, and soon there are others on the scene, including the German wife of a professor who compares human behaviour with that of the monkeys.
