In 1962, Italian comic book writers Angela and Luciana Giussani invented fumetti neri ("black comics") with Diabolik, a wildly popular crime series starring an elusive master thief. Within just a few years, the comic was adapted into a psychedelic feature film - released internationally as Danger: Diabolik - directed by a true maestro of Italian genre cinema in Mario Bava (Blood and Black Lace) and starring John Phillip Law (Death Rides a Horse) in the title role. Somewhere in Europe, Inspector Ginko (Michel Piccoli) is the police officer charged with overseeing the transportation of $10 million from a bank, determined to stop it from falling into the hands of the infamous thief known as Diabolik (Law) and his accomplice Eva Kant (Marisa Mell).
