Martine Carol plays the title character in the comedy melodrama Nathalie. The heroine is a professional model who becomes innocently mixed up in a robbery/murder case. Deciding to play detective, Nathalie leads both the authorities and the underworld on a merry chase. She also wins the heart of police inspector Franck (Michel Piccoli), who does his best to shield her from the evil machinations of criminal mastermind Coco (Philippe Clay). A big hit in France, Nathalie also did quite well in the U.S. under the title Foxiest Girl in Paris.
