It’s winter in Paris and Madeleine is having problems at school.
A new girl, Mirabelle, is bullying her. Then Madeleine is befriended by Madame Bonbon, who runs an alluring-looking sweet shop.
The sweets Madame Bonbon gives Madeleine have the most bewitching effect, at first making her feel much stronger and able to confront Mirabelle.
However, soon they start drawing her into a strange, enchanted world from which she cannot escape.
Will Madame Pamplemousse and Camembert be able to rescue Madeleine?
