In this erotic drama based on an infamous novel by the Marquis de Sade, two sisters are raised in a convent, where they suffer all manner of abuse. The girls are eventually expelled for misbehavior, and make their way to London, where they find work in a brothel. One is able to adjust to the realities of her new life, but the other rebels and runs away, only to fall victim to an especially cruel fate. Justine, which was also released under the title Cruel Passion, stars Koo Stark, who gained notoriety in 1982 after it became public knowledge that she had a brief affair with Britain's Prince Andrew.
