Cleo's witch is sometimes a little scatterbrained, so it's just as well she has a cat to keep her in order. Cleo has her paws full making sure that her witch Elodie's do-it-yourself charms are worth the boxes they're packed in. Her witch isn't always the best flier, either, which makes living in a treehouse a little challenging. Elodie just needs to get her new batch of charms made, but her cat keeps interrupting the process: fighting with other cats, dislodging pumpkins and getting her claws into everything. But when Cleo and Elodie find a hunter and his hellhounds risking wildfire in the forest on Halloween morning, the cat and her witch have their work cut out to make sure the Wild Hunt doesn't bring terror to the nearby town.
