In a working-class immigrant neighborhood slated for demolition, Jo, the son of Ali, known as the Rescuer from the Algerian war, lives idle and delinquent, committing small assaults to pay for his drugs. One day, while attacking Slim's bar, he is arrested by Ben, a young beur cop torn between his roots and the imperatives of his mission to maintain public order. Giving in to the respect and friendship he feels for Ali, Ben agrees to release his son. But alas, far from calming down, Jo drifts deeper into violence, until the inevitable drama.
