Because of his kindness and philanthropy, Dr. Praetorius enjoys great popularity among patients, the medical staff and the student body alike. Only his colleague professor Speiter begrudges his success.
When his patient Maria Violetta wants to commit suicide because of an extramarital pregnancy, Prätorius takes care of the young woman. He attempts to break the news gently to her father but the latter mistakes him for a more than welcome admirer of his daughter. Since a deep affection has developed between the doctor and his patient, the two eventually marry. Their married bliss fuels the envy of professor Speiter who believes he can uncover dark points from the doctor's past. But Praetorius succeeds in refuting all allegations before a court of honor with wit and astonishing revelations.
Goetz's production has been noted for highlighting the particularly tragicomic and melancholic moments of the play. Humanistic values are emphasized and the issues of abortion and capital punishment are critically examined. In addition, Goetz gives prominence to the protagonist's elusive search for the microbe of human stupidity, which he believes to be the cause of envy, hatred and war.
