It all starts with a snap idea. Peter Schönfeld (Dieter Mann), a good husband, whose excess of virtue seems suspicious, is to be subjected to a loyalty test. Rosemarie (Karin Ugwoski), the best friend of Peter's wife Regina (Margot Busse), wants to dissuade the straw widower from the path of virtue with all sorts of tricks and erotic finesse. This leads to all kinds of confusion and confusion. So it will be interesting to see whether the "hero" of the play Peter Schönfeld can finally say: Yes, I am such a man!
