The earls of Burgenland train for the annual Castle tournament with dogged determination. At this year's games, Countess Waldegund von Niederlagen wants to beat Earl Günther von Siebensieg and his dragon Füffü once and for all. To be able to commit to the upcoming fight, the Countess starts looking for a nanny to attend to her two kids, Wentzel and Waltraud. Miss Mallow, a slightly sprawling and overly enthusiastic woman, applies for the job. But as it seems, Miss Mallow doesn't fit in with her new surroundings. The castle life is far from what she seems appropriate for the kids, something she's not afraid to point out.
