Academy Award winner Jean Dujardin (The Artist) stars as French police magistrate Pierre Michel, who waged an obsessive six-year battle to bring down Marseilles' infamous "French Connection" drug ring.

Marseille, 1975. Pierre Michel, a young police magistrate with a wife and children, has just been transferred to help crack down on the city’s organized crime. He decides to take on the French Connection, a Mafia-run operation that exports heroin all over the world. Not paying heed to any warnings, he leads a one-man campaign against Mafia kingpin Gaëtan Zampa, the most untouchable godfather of all. But Pierre Michel soon discovers that to get results he will have to change his methods.
