American Anarchist is the story of The Anarchist Cookbook, and the role it’s played in the life of its author, William Powell. Written as a teenager—and first published at the apex of the counterculture of the 1970s to protest the United States’ involvement in the Vietnam War—part manifesto, part bomb-making manual, The Anarchist Cookbook went on to sell over 2 million copies and has been associated with decades of anti-government attacks, abortion clinic bombings, school shootings, and domestic terrorism. Powell, now 65 and haunted by his creation, confronts his work and its consequences. We see how in 1976, 5 years after writing the book, he left the United States, leading an itinerant life and later becoming a teacher for emotionally disturbed children, the same sorts of kids that carried the Columbine High School massacre, the Colorado high school shooting and the 2012 Aurora shooting. American Anarchist is a cautionary tale of youthful rebellion, unforeseen consequences, and a universal story of an older person wrestling with their younger past.
