Last year, film-maker Dan Murdoch met members of the Black Panthers when they and the Ku Klux Klan organised rival protests in South Carolina. Now, in a follow up to KKK: The Fight For White Supremacy, Dan returns to America to take a closer look at the Black Liberation Movement. He re-visits some of the people he came across, following them more closely to explore their motivations and ambitions, and the impact of the movement in the USA today.
