A fairy tale based on Charles Deulin's story about how dancing was forbidden in the castle, yet every morning there was a pile of worn-out shoes in the princesses' chambers. The king had great trouble with his daughters, Princess Maria, Klara, and Lina. They always got up at noon, complaining of headaches and fatigue, looking pale and emaciated. But at night... The secret of the three princesses is revealed by the basket maker Peter. If Peter had not fallen in love with the youngest of the princesses, no one would ever have found out where she and her two sisters spent their nights, and why it was so difficult to wake them up in the morning. Peter is helped by a fairy who, as it turns out, is the princesses' mother.
