In the boudoir of a sequestered country house, a young virgin is ruthlessly schooled in evil. Indoctrinated by her amoral tutors in the ways of sexual perversion, fornication, murder, incest, atheism and complete self-gratification, she takes part with growing abandon in a series of violent erotic orgies which culminates with the flagellation and torture of her own mother - her final act of liberation. "Philosophy In The Boudoir" is perhaps the most concise and representative text out of all the Marquis de Sade's works, containing his notorious doctrine of libertinage expounded in full, coupled with relentless bursts of savage, orgiastic eroticism, cruelty, and violent sexuality. The renegade philosophies put forward here would later rank amongst the main cornerstones of Andre Breton's Surrealist manifesto.
