This complex thriller follows the fatalistic relationship between two men: Maurice, a crook just out of prison and Silien (Belmondo), who may or may not be a Doulos (a kind of high-class informer). Maurice, wasting no time, immediately begins to put himself on the wrong side of the law, setting up a number of robberies with the help of Silien, whom he begins to suspect is a police informer. A spellbinding New Wave noir from director Jean-Pierre Melville (LE SAMOURAI).
