Flesh of the Orchid (1975)

Looking for a sexy sampling of Charlotte Rampling? La Chair de l'orchidée (1974) is your ticket to paradise. It stars Charlotte as a troubled young heiress who's been raised by a real ogre of an auntie—played with gleeful meanness by Edwige Feuillère—who wants nothing more than to keep her charge prisoner so she herself can snatch the family scratch. To pull off her master plan, Edwige keeps Charlotte in the boobyhatch, but the batty beauty has plans to free herself (and her spectacular mams). Every man who tries to help Charlotte ends up dead, but that doesn't stop her from trying her luck . . . and when she meets a guy on the run from killers, she starts to think she's found herself a partner.
