The infamous Marquis de Sade has been imprisoned in the asylum of Charenton for endangering public morals. As a form of therapy, the hospital’s patients are allowed to take part in plays, and de Sade sets out to dramatize the death of the French revolutionary Jean-Paul Marat, who was murdered in his bath. With its cast of sociopaths, schizophrenics, and narcoleptics, Marat/Sade is a bawdy and outrageous play where madness and reason seem inseparable. It is a depiction of the violence of modern society while asking whether true revolution comes from changing society or changing oneself.
