The Sicilian Clan
Roger Santet is really a murderer sprung from prison by the Sicilian clan headed by the Vittorio Manalese that is aging. They conspire to steal a massive cache of jewels. Since they are currently getting ready for the heist, the mobster's American friend Tony Nicosia suggests that a better way to find the rocks is to ditch the transport plane whenever it's on the way to New York. The dogged inspector Le Goff is currently using the tools to thwart their plans. Although heist is so successful, Santet finds himself trapped with the Daughter in Law of Manalese
