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.
