Big day for Freshman Class 1: it's their first Physical Education class, with its share of surprises for the girls. And it's the class president election… It is also a trying day for Bellanger: it's the day of his nephew's disciplinary board hearing, and he needs to keep a close eye on the trials and tribulations of Miss Couret, the new English teacher, who is trying to fit in.

Bellanger is excited to be back in at school again after the Christmas break… But today, the boys are restless. It infuriates Michèle, who'd like to know what "makes you blind" and can't stand being treated like a little girl. When the source of all this commotion is revealed in the middle of English class, Couret and Bellanger have to team up to deal with this disciplinary issue together.
