For more than 15 years, two Marseille friends and criminals battle the law, rival gangs, prison authorities and even mined beaches in order to survive.

Two thieves, Hugo Sennart and Yan Kuq, wanted by the same police inspector, cross paths by chance.

A former bank robber is released after 10 years in prison. He gets help from a social-worker, but gets harassed by an old cop from his past.

Police inspector Léonetti, a tough, efficient policeman, has been sent to a second-rate police station after being reprimanded. There he is given a partner, young and beautiful Jeanne Dumas. The duo are soon assigned a very difficult mission: to find a man whose evidence is instrumental in convicting a murderer. They start searching throughout Paris.
