Warren Beatty plays a cheeky young playboy with a taste for gambling who devises the ultimate scheme to cheat the casinos. After finding out that all of the casinos use the same playing card manufacturer, he breaks in and marks the kaleidoscopic pattern on printing plates for the cards. Soon the winnings mount up as he travels across Europe beating the odds. But Barney's troubles begin when he falls for the swinging fashion designer Angel (Susannah York), who discovers his deception. Her father is a Scotland Yard inspector who offers Barney a deal. He will keep quiet about the cards if Barney helps him catch international drug smuggler Harry Dominion through a high-stakes poker game... directed by Jack Smight in 1966 and starring Warren Beatty and Jane Birkin.
