This story of the King family -- their stormy, God inspired, romantic and often adventurous lives, adapts its title from Mark 3:17 of the Bible, because A. D. and Martin King were fiery preachers. It explores provocative episodes of the civil rights movement, in large part through the remembrances that A. D. King shared with his daughter Alveda. "Sons of Thunder" examines the civil rights movement's triumphs against extraordinary odds and the human flaws and frailties that give texture to this explosive chapter of our history; recasting the story in a fresh, compelling light.
