America's most infamous supremacist group - the Ku Klux Klan - says they are in the midst of a revival, with a surge in membership and cross lightings across the Deep South. Filmmaker Dan Murdoch meets the leaders of the Loyal White Knights, who claim to be the largest Klan chapter, to witness first-hand their secretive rituals and hear about why their members choose to don the hood. Klansmen say they are not violent. But when a 21-year-old white man walks into a church in Charleston, South Carolina, and massacres nine black worshippers saying he wants to start a race war, he crystallises the danger of the white supremacist ideology. The film follows events as protests erupt and Black Power groups, including the New Black Panthers, take to the streets to preach their own agenda of black supremacy. And when the Ku Klux Klan and the New Black Panthers organise rival protests in the South Carolina capital, the two extreme visions of America come violently face to face.
