Vincent Mandel (Yvan Attal), is a photographer, caught up in an ugly divorce and fighting for custody of his children. His already troubled existence is blown apart by the appearance of a ghost from his past: Joseph Plender (Clovis Cornillac). Seductive, sympathetic, Plender is nonetheless utterly ruthless, a predator motivated by pure hatred of former classmate Vincent, and hungry for vengeance

Blackmail, kidnap, murder... Vincent is driven into hell and left with only one desperate hope - fighting Plender by his own rules, beating him at his own deadly game.
