Day after day, for an entire school year, Mariana Otero filmed students in a middle school located in the heart of an underpriveleged Paris suburb. In the classrooms, in the principal's office, during advisory and disciplinary board meetings, when things were going well and when things were going badly: Otero captured the every-day, extraordinary and dramatic moments of life at school. The school, with all its rules, penalities and rewards, is where the ten to sixteen year old students learn how to live in society. The series reveals the complexity of the relationship these young people, mostly from troubled socioeconomic backgrounds, have with the "school law".
