This film is about a couple of retired jewel thieves and an FBI agent who is destined to catch them. While beginning their retirement, Max Burdett and Lola Cirillo are met by FBI agent Stanley Lloyd, who was made a fool by the thieves after they stole a rare jewel that was handcuffed to his wrist. Believing the thieves aren't really there to retire, he begins to watch them because a Diamond Cruise off the island coast where they are staying has the Napoleon number three diamond on the ship. When questioned, Burdett doesn't seem to know anything about the diamond, but when propositioned by a wealthy tycoon, he cannot refuse to steal it. So Burdett sets off on a plan to steal the diamond, but can he steal it right under Lloyd's nose again?—thexotherxchris
