L'élève Ducobu

Ducobu is expelled from every school he attends. Eventually, his father is forced to move so his son can be admitted to a school in Saint-Potache where, threatened with being sent to boarding school, the lazy brat develops various tricks in order to obtain good grades. His teacher, Mr. Latouche, is vocal in his admiration for his new student, but Leonie, the class brain, fears this new rival. Everything changes when Latouche discovers Ducobu's bad boy reputation when he talks to his colleagues from the boy's previous schools. Immediately, the teacher declares war and tries to get him expelled. But Ducobu has more than one trick up his sleeve.
