Jean Gabin plays Charles, an aging gangster, newly released from prison. In fine Bogart tradition, the unrepentant Charles immediately sets to work planning a major casino heist in Cannes. His go-between for this endeavor is a chorus girl, whom Charles's associate Francis (Alain Delon) beds in order to win her confidence. This rapidly-paced suspenser was based on a novel by John Trinian. When first distributed in the US, the film travelled under the title Any Number Can Win. ~ Hal Erickson, All Movie Guide
