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.

Annick is disgusted by the upcoming frog dissection, and suggests stealing the batrachians, in exchange for 1h of tutoring with her. The boys need nothing more to take on the challenge! "The VP's niece" is again sidelined from the plans. Between two trips to the restroom because of sharp period pains, Simone tells Michèle she should show them she's not a goody-two-shoes by stealing them herself.
