Serge Buren is a legendary cop, surrounded by a group of young cops who employ unconventional methods. Who cares if they use baseball bats or "forget" the rules during spectacular arrests, when they achieve such great results. Then a gang of murderous bank robbers enters the scene, breaking into Parisian banks and jewelry stores with disconcerting ease, employing weapons of war and implacable scenarios. Confronted by so much ingenuity and brutality, Buren and his squad find themselves facing a delicate situation: will their expeditive methods suffice to stop criminals who are even more Machiavellian than the cops themselves?
