Corey (Alain Delon) is the young gun in the French underworld who has just been released from prison. Escaped convict Vogel (Gian-Maria Volonté) hides in the trunk of Corey's car. The two enlist the help of an alcoholic former cop (Yves Montand) for an elaborate jewelry-store robbery. Police inspector Mattei (Bourvil) whom Vogel escaped in the beginning of the film is on the case trying to recapture the criminals. He is not opposed to using blackmail techniques to get answers out of the unwilling witnesses and criminals brought in for questioning. ~ Dan Pavlides, Rovi
