TV version of Curth Flatow's stage play starring Johannes Heesters and his wife Simone Rethel.

The landowner Klapproth would love to have his nephew Alfred, whom he promises to support financially to set up a business, show him the inside of an insane asylum and experience real lunatics. Alfred's friend Ernst Kissling recommends that he show his uncle the Pension Schöller, whose guests are rather eccentric. Landowner Klapproth, who really does think the guests are lunatics, has a great time. However, the situation escalates when Klapproth returns to his estate and is visited by these supposed lunatics.

Willi Clark (Harald Juhnke) and Al Lewis (Wolfgang Spier) were once one of the greatest comedian duos. They delighted audiences for over forty years, but one day the friends broke up over a small argument. When the television approaches them and asks them to perform one of their most famous laughing numbers again, the two are immediately enthusiastic. In the face of the fact that they are finally back in the limelight, they forget their old quarrel. However, the peace does not last long, because already during the rehearsals there are new turbulent arguments between the two bartenders .
