The young emperor Joseph II of Austria and Hungary is not interested in romance and marriage, and every time his mother makes arrangements for him to meet eligible young ladies, he escapes under some pretense. This time he is off on a 'tour of inspection' with his trusted friend von Kleber. Things become complicated when von Kleber, pretending to be the emperor so as to protect the real Joseph from discovery, falls in love with Christine, the landlady of their lodgings. And when Christine later writes to the emperor, her letter is read by the mother of the real emperor, as keen as ever to see him getting married, and so the lady is invited to the imperial court.
