Good dope is becoming rare in the North of Paris. Drugstores are being raided by junkies and gangs are nervous, fighting each others: the 'Viets', the 'Blackies', the 'Arabs', the neo-nazis 'Justiciers' and some mean gays. Vincent (Daniel Auteuil) is the good cop coming from Marseilles where he was a gangster. He's a soft method guy but also kicks assses hard and throw lethal dialog lines when needed. With the precious help of 'l'Arbalète'* (Marisa Berenson**), a tox' prostitute ex-member of Vincent's former gang, he will try to put order in that mess. There's also a violent and racist cop (Marcel Bozzuffi), Algeria veteran with hard methods, whose role could be more than to protect and to serve.

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.
