Diamant 13 (Diamond 13)

Diamond 13 traces the slow descent into hell of a policeman faced with a society ruled by money, the corruption of his colleagues and the shadow of death. Mat (Gérard Depardieu) is a member of the 13th night division of the criminal police. His lifelong friend, Franck Novak (Olivier Marchal) - who works for the drug squad - has been involved for some time in shady dealings. But the confines of morality are easily crossed and when Franck goes too far Mat has to take matters into his own hands.
