Princess Josephine certainly has her moods and idiosyncrasies. Her father, King Eduard, misunderstands her one day and believes he has to look for a husband for his daughter. He decides on the court music teacher Adelung. But Josephine is against it; she wants a man as a husband who can play the grumbling iron. But then she falls in love with the king of the neighboring kingdom, Jonathan, who in turn only wants a wife who can bake peppernuts.
