“The starting point for this project was a blunder by the police that I filmed ten years ago. The video spread and caused the policemen to be suspended.” A member of the Kourtrajme collective, Ladj Ly offers a war movie, like a real blow: an assessment of the situation and an alarm call that tells us about the place of children in difficult districts. Victor Hugo, 157 years earlier, situated his “Misérables” in this same district of Montfermeil.
