Justine: A Matter of Innocence (1980)

Teenage Justine has just learned that her father has died. Leaving her exclusive French boarding school and returning to the U.S., Justine goes to live with her estranged but extremely wealthy uncle Steven on his vast New England estate. Upon her arrival, the beautiful though naive Justine soon finds that she is an object of lust to all those she meets, man and woman alike. As she slowly unravels her own sensual desires and transforms from innocent virgin to voluptuous vixen, she begins to feel an unexpected type of emotional stirring: a desire for romance, which might just happen in the unlikeliest of circumstances.
