Manon (Catherine Deneuve) is an amoral, free spirit who uses sex to surround herself in relatively luxurious surroundings. The mistress of a wealthy man, she meets a handsome young reporter (Sami Frey) on a flight from Hong Kong to Paris. She gives the older man the boot before slipping into a hot bathtub with her new love, the reporter. Her brother Jean-Paul (Jean Claude Brialey) puts out the word to rich men that his hot-to-trot sister is back in town. She willingly allows herself to be used for sex to justify her lifestyle. The reporter loses his job and Manon takes up with another wealthy client, seeing the reporter on the side. Men continue to fall for the beautiful, opportunistic Manon who is more interested in Mr. Right Now than Mr. Right.
