Description:
—Justine is a nubile young virgin cast out of a French orphanage and thrust into a depraved world of prostitution, predatory lesbians, a fugitive murderess, bondage, branding, and one supremely sadistic monk. It’s a twisted tale of strange desires, perverse pleasures and the ultimate corruption of innocence as told by the Marquis de Sade.

—Justine (Koo Stark) wishes to remain innocent and virginal, but instead slips into a life of debauchery, torture, whipping, slavery and salaciousness. Meanwhile, her brazen, flirtatious and liberated sister Juliette ironically receives nothing but happiness and reward for her wanton behavior. Justine’s only possible hope of true love and salvation is one of her sister’s former lovers, the suave and elegant Lord Carlisle (Martin Potter). But is he as virtuous as he seems?
