An innocent girl spends a weekend on the private island of a libertine woman and her stepbrother, but soon finds herself entangled in a web of sadistic sexual experiments.

Eugenie, a beautiful but shy young girl, lives with her stepfather, a famous writer specializing in stories of erotica. One day she happens to read one of his erotic books and its power so affects her that begins to find herself sexually attracted to her stepfather. He notices this, and eventually brings her into his dark world of sexual perversion and murder.—De Sade

Seductive Madame Saint Ange approaches young and innocent Eugenie with an offer she can't refuse: follow her to her private island for an eye-opening, experience-filled weekend. But inspired by Marquis de Sade's taboo-breaking writings, the elegant lady plans to introduce sweet Eugenie to the unknown realm of pleasure and pain. As the inexperienced Eugenie yields to temptation and embraces her intimate desires in the secluded villa of sin, she enters a world of potent hallucinogens, obsessive sadomasochism, and erotic violence. And when sinister cult leader Dolmance and his sadists arrive, the perverted hostess and her sultry plaything will discover the boundaries of kink and perversion.—Nick Riganas
