It's 1937. The Nazi threat looms. The world is on the brink of war. Winston Churchill is tasked with creating a covert British Intelligence Agency. The infamous satanist Aleister Crowley, branded "The Wickedest Man Alive," and his gang of agent provocateurs, including descendants of Houdini and Van Helsing, are persuaded by Churchill to help infiltrate the shadowy depths of the Nazi Occultist Secret Societies, using dark arts and the supernatural to fight evil on its own terms.
