This pornographic film is of historical interest as it marks the first film produced in Holland with full frontal nudity for both sexes. While it has its share of graphically depicted sexual scenes, it also has a story. Released from prison for sex offences, a young man moves into an apartment house with very thin walls, and the sounds he hears make him believe his neighbors are having sex all the time. He has a married neighbor, a professor. The professor arranges things so that his wife can meet and seduce the sex offender, possibly so that the humiliating revenge of impotence can be visited upon him.
