The twelfth grade students, excited and eager to have fun, experience, in addition to the excitement caused by the imminent baccalaureate exam, tensions sparked by the appearance of the new French teacher, "cool, young, dark-haired, tall...", in whom the girls discover an adonis, and the boys a rival.

This novelty gives rise to conflict situations, for the smoothing of which it is necessary to intervene even the headmistress, whose interest is also directed towards the young teacher. The naivety from which the misunderstandings erupt creates the comic of the situation, making up an original, cheerful and lively show.

Both the events themselves and the way they are staged, clothe the show in a cloak of universality, making it accessible to viewers, who, regardless of age, will easily be able to identify or empathize with any of the characters.
