The kind-hearted but slightly awkward Dr. Eduard Frank is transferred to a girls' boarding school in Carinthia. He soon finds out that his upper class consists of a bunch of cheeky rebels led by the bright Princess Margret. With their pranks, the girls bring poor Dr. Frank to the brink of despair. He cannot expect any help from the spinsters' teaching staff. The only one that Dr. Frank keeps at the boarding school is the courageous sports teacher Angelika. When Margret notices this sympathy, she fakes a fiery love exchange between the two.
