In Paris, France, there is a special force in the police system-the Juvenile Police Force (Juvenile Protection Unit), which is related to drug abuse, drug trafficking, drug abuse, injury and abuse, but only one standard or target is to take over, that is, a large group of young people. At work, they get to the bottom of the victims and suspects, chasing after them, just to find out the truth and give the children a free and healthy growth sky. In life, they argue loudly for their respective political views, and they also suffer from the joys and sorrows and tribulations of their lives. They are a very ordinary group of people, and they are doing a significant job. The film won the 2011 Cannes International Film Festival jury Best Picture Award, the French Caesar Award for Best Editing and the most promising Actress Award (Naidra Ayadi).
