A king is married to a woman with golden hair. The queen falls ill, and realising she’s going to die she asks her husband that, if he’d ever remarry, it would be only to a woman as beautiful as her with the same golden hair. Unfortunately, the only one to fit the description is his own daughter, Princess Lotte. He decides to marry her. All she can do is flee. She dirties her face and hands with soot and escapes.
