On the French Riviera, a reformed jewel thief falls for a wealthy American woman, who suspects he's up to his old tricks when a rash of jewel thefts occur. Oscar-winning photography by Robert Burks, a notable fireworks scene, and snappy dialogue. A change of pace for Hitchcock, this charming comedy-thriller proved to be as popular as his other efforts. Based on the novel by David Dodge. Kelly met future husband Prince Rainier during a photo shoot while she was attending the Cannes Film Festival.
