The penible court councillor Geiger finds it like sheds from his eyes: the 18-year-old Mariandl, who applied for a music study with him, is his own daughter. Repentantly he decides to catch up with his father's duties and travels to Dürnstein, where he met Mariandl's mother Marianne 19 years ago. This runs an inn, which, however, is close to the bust because of lack of guests. Marianne is forced to marry a wealthy hotelier. However, when Geiger suddenly stands in front of her, old feelings flare up again and between Geiger's secretary Peter and Mariandl more than just a good friendship.
