To Catch A Thief (La main Au Collet-1955) is a Hitchcock-directed, entertaining comedy / thriller concerning jewel heists by "The Cat" on the French Riviera.
John Robie (Cary Grant) is a notorious but retired jewel thief or "cat burglar" nicknamed "The Cat", who now tends to his vineyards in the South of France. A series of robberies that closely resemble his style leads the police to believe that the Cat is up to his old tricks again.
The American expatriate hero has to catch the real cat burglar (a 'she-cat') during a rash of robberies before he is caught himself, while the heroine (Grace Kelly) is on a quest to 'catch' him - first as the burglar, and then as a husband.
Frances: (She sits alluringly on the couch, displaying both her necklace and bare decolletage.) Give up, John. Admit who you are. Even in this light, I can tell where your eyes are looking. (He sits down.) Look, John. Hold them. Diamonds. The only thing in the world you can't resist. Then tell me you don't know what I'm talking about. (She kisses his fingers, one by one.) (She puts her necklace in the palm of his hand.) Ever had a better offer in your whole life? One with everything?
John: I've never had a crazier one.
Frances: Just as long as you're satisfied.
John: You know as well as I do. This necklace is imitation.
Frances: Well, I'm not. (They kiss. The white-hot peak of the colorful fireworks exhibition bursts in a vibrant closeup.)
