The Marquis de Sade's writings melt the screen in director Jesus Franco's unsettling tale about perversion and amorality, which finds shy Eugénie Radeck (Soledad Miranda) drawn into a realm of sex and sadism after reading a volume of erotica penned by her stepfather (Paul Muller). Before you can say "kinky," the two embark on a spree of seduction and destruction across Europe. Andrés Monales and Greta Schmidt also star.
