After 5 years, 16-year-old Gaby Roberge, returned to Sainte-Victoire High School with a rebellious air and a dirty attitude. Gaby can't stop thinking about graduating and moving on to CÉGEP where she will meet more intelligent young people. Peggy Lamothe, the school principal, decided to take Gaby under her wing so she could take advantage of her last year in college. She forces Gaby to integrate with the young people in her life and be less aggressive and more social.
