When the young detective Paul Nerteaux finds the third slashed female corpse of illegal Turkish immigrants, he decides to ask for support to the experienced dark retired detective Jean-Louis Schiffer to chase the serial killer. Together, they infiltrate in the Turkish mafia trying to find the answer to the crimes. Meanwhile, the worker Anna Heymes is being submitted to a brain treatment and has severe headaches and glimpses of memories and visions. When these two parallel events collide, disclose that the Turkish organization “The Wolves” is behind them.
Lambert, a burned-out case, works the night shift at a gas station, rarely speaking, living alone, drinking. Bensoussan, raised in foster homes, now a small-time pusher for a bar owner named Rashid, comes to the station needing a spark plug for a stolen Moped. He and Lambert connect somehow, and a few days later, they go for a drink. The young man is too cavalier, and when he swipes Rashid’s fancy motorcycle a couple of times, he’s expendable. Lambert decides to avenge the young man and seeks information from Lola, a punk who knew Bensoussan. With surprising perseverance, she pierces Lambert’s shell; he starts to feel again, tells Lola his story, and finds new enthusiasm for life.
