Sam Dunn, a 30-year-old headbanger-turned-anthropoligist, sets out on a quest to explore Heavy Metal's origins and cultural impace. His mission? To get to the bottom of one of one burning question: Why is Heavy Metal music so beloved by its devoted fans and yet so controversal? This ground-breaking film examines the history of Heavy Metal stereotypes and illuminates the truth behind the music. Witness performances and candid interviews with metal icons of legendary bands, including Black Sabbath, Iron Maiden, Slayer, Twisted Sister, Motley Crue, Motorhead, Rob Zombie, Alice Cooper, Ronnie James Dio, Rage Against The Machine and Rush, as well as extermists like Slipknot, Cannibal Corpse and more. Shot on location in the U.K., Germany, Norway, Canada and The U.S., this documentary is an exhilarating tribute to Metal's dark side, and an outsider's window into a complex spectacle and fascinating subculture.
