With her three tame weasels, she survives by going to steal food from the castle of the sinister regent Tristain, who usurps the throne. One fine day, to escape the guards who are chasing her, Pil disguises herself by putting on a princess dress. Here she is, despite herself, embarked on a crazy and delirious quest to save Roland, the heir to the throne who has been enchanted and transformed into... chapoul (half cat, half chicken). An adventure that will shake up the entire kingdom and teach Pil that nobility can be found in each of us.
