Cary Grant plays John Robie, a reformed jewel thief once known as "The Cat." When he is suspected of new gem thefts in the luxury hotels of the French Riviera, Robie sees a plot to clear himself after meeting pampered heiress Frances (Grace Kelly). Romantic sparks fly as the suspense builds in this essential VistaVision classic, which nabbed an Oscar for Best Cinematography, Colour (1955).
