Assigned to work alongside unethical police veterans Chris and Gwada in Paris' Anti-Crime Brigade, Brigadier Stéphane Ruiz, a recent transplant to the working-class suburb of Montfermeil, struggles to establish a working relationship with influential community leaders while attempting to maintain some semblance of peace between his disreputable team and the citizens of the local housing projects. When what should be a simple arrest goes tragically awry, the three officers must individually reconcile with the aftermath of their actions while angling to keep the neighborhood from retaliating with mob violence.
