Mesrine: Killer Instinct -- the first of two parts -- charts the outlaw odyssey of Jacques Mesrine (Vincent Cassel), the legendary French gangster of the 1960s and 1970s who came to be known as French Public Enemy No. 1 and The Man of a Thousand Faces. Infamous for his bravado and outrageously daring prison escapes, Mesrine carried out numerous robberies, kidnappings and murders in a criminal career that spanned continents until he was shot dead in 1979 by France's notorious anti-gang unit. Thirty years after his death, his infamy lives on. Mesrine was helped along the way by beautiful and equally reckless Jeanne Schneider (CÃ©cile de France), a Bonnie to match his Clyde. Mesrine made up his own epic, between romanticism and cruelty, flamboyance and tragedy. Written by Music Box Films
