It all begins with a crazy idea. Peter Schönfeld, a good husband whose excess of virtue already seems suspicious, is to be subjected to a fidelity test. Rosemarie, Peter's wife Regina's best friend, wants to dissuade the straw widower from the path of virtue with all kinds of tricks and erotic finesse. This leads to all kinds of confusion and mix-ups, to which Uncle Ewald, whose motto is "If you have worries, you need a liqueur", and his daughter Gisela, the "model", as well as Peter's neighbor, the amateur nude photographer Konrad Förster, intentionally and unintentionally contribute. So it will be interesting to see whether the "hero" of the play, Peter Schönfeld, can still say at the end: "Yes, that's the kind of man I am!".
