To Catch a Thief (1955)

On the French Riviera, a new run of jewel robberies points suspicion toward John Robie, a retired thief once known as The Cat. Determined to prove he is not behind the crimes, Robie tries to catch the copycat burglar himself. His pursuit draws in a wealthy widow and her beguiling daughter, turning the search for the real thief into a risky game of deception, attraction, and suspicion.
