Cherchez la femme (1955)

Barbara Van Looren is the lively, clever daughter of the well-known shipowner. For her, life is a breeze, even when she's kidnapped by Mike Cortez's men. A young journalist, Mercier, who tried to defend her and was forced to follow her, doesn't share her optimism and manages to escape. Barbara is sequestered because her father has caught wind of a diamond deal. If he renounces the customs action, his daughter will be returned to him. Mercier, with the help of a couple of loyal friends, discovers the instigator of the traffic, a member of the board of directors, and finds Barbara, still as petulant as ever.
