Jean Reno and Vincent Cassel star in this grisly French crime thriller, co-written and directed by Mathieu Kassovitz (La Haine) and newly restored in 4K.

Two French policemen - one an experienced detective, the other a reckless rookie - are brought together by the clues from their respective cases. As more murders occur, the two cops uncover an increasing number of horrific details that all point to a dark conspiracy.
