Im singenden Rössel am Königssee (1963)

Things are hectic at the "Black and White Horse Inn" on Lake Königssee. Cordula, the young owner of the long-established family business, has just learned that her father, who died five years ago, included a clause in his will: If she fails to find a husband in the hospitality industry, she must hand the "horse" over to her greedy uncle Simon. He, in turn, had hidden the will in order to present it to Cordula now, just before the deadline. She has two weeks to fulfill her father's wishes. While she has an ideal candidate in her charming head waiter, Franz, the much-loved man is completely unaware that his boss has secretly been in love with him for a long time. Instead, Franz believes he has found the woman of his life in the pretty hotel management student Monika.
