A new school year starts for Ducobu ! At Saint Potache School, a special election will be held to elect the student president. It’s the beginning of a crazy electoral campaign in which the two main opponents will launch themselves: Ducobu and Léonie. With the help of his friend Kitrish and his many gadgets, Ducobu cheats like never before and wins the election. Amusement park in the courtyard, return of the siesta, suppression of vegetables in the canteen… for Latouche, enough is enough!
