Madame Croquemitaine is an evil fairy who steals little children and transforms them into various vegetable plants: cabbages, asparagus, radishes, carrots... which grow and multiply in her vegetable garden. But little Geoffroy, whose brothers and sisters have been taken away by Mrs. Croquemitaine, implores with all his might the fairy Aimable, who comes to his aid and gives him a magic wand that will help him overcome all the obstacles that separate him from his captive brothers and sisters.
