Dr. Hartwig has settled in a small town as a doctor. One day the magical Ursel Daxenmeyer appears in his practice. Dr. Hartwig falls in love with her and wants to marry her. Beforehand, however, various obstacles have to be cleared out of the way. A very special obstacle is Ursula's father, Eusebius Daxenmeyer. He deals with mixed goods and is also a hypochondriac, that is, an ill patient. No one can tell him his imagination that he is deadly ill.
