West German crime film directed by Rolf Olsen and starring Curd Jürgens, Andrea Rau and Corny Collins. It is set in the red-light district of St. Pauli in Hamburg.

The Film begins with an emphatically serious discussion between Kolle, the sex researcher Professor Hans Giese, and the psychologist Wolfgang Hochheimer. After that follow the first play scenes. In a buoyant conversation, two model cases of sexual difficulties in marriage and their causes are discussed. A newlywed couple one the one side and a couple already married for seven years on the other side discuss about their problems. The words are illustrated by play scenes, short comments which point to the consequences of a lack of sexual education are inserted in between. With the newlyweds, the premature orgasm of the husband causes his wife woes as she is missing the loving foreplay and aftermath. The second husband, an architect who has become father of two children in the meantime, in contrast, neglects his wife in favour of his job.

A movie with three episodes directed by Hannes Dahlberg, Roger Fritz and Eckhart Schmidt.
