Francois Marin (François Bégaudeau) is a French language and literature teacher at an inner-city Paris high school. As the new school year begins, he introduces himself to his new class and begins the arduous process of reaching out to each of them. Marin encounters his share of problem students, teen violence, ethnic tensions between classmates and education barriers within the group, all of which test his patience and -- more importantly -- his resolve as an educator.
