Historian and journalist Tony Perrottet unearths sexual stories from throughout the ages. The series is modeled on the "secret cabinets" in Victorian museums, where medieval chastity belts, Renaissance pornography and perverse novels by the Marquis de Sade were hidden. Each episode will answer a burning question: How did Napoleon's penis end up in suburban New Jersey? Are champagne glasses modeled on Marie-Antoinette's breasts? How did you behave at one of Caligula's orgies? And what were Casanova's best pick-up lines?
