Cruel Passion (also known as Justine) is a 1977 film starring Koo Stark, Martin Potter, Lydia Lisle, and Katherine Kath.

It was directed by Chris Boger and based on the 1791 novel Justine by the Marquis de Sade.

[1] Justine is a young virgin thrown out of a French orphanage and into the depraved world of prostitution.

She slips into a life of debauchery, torture, whipping, slavery and salaciousness while her brazen, flirtatious and liberated sister Juliette ironically receives nothing but happiness and reward for her wanton behavior.
