Description: On September 15, 1963, a bomb destroyed a black church in Birmingham, Alabama, killing four young girls who were there for Sunday school. It was a crime that shocked the nation -- and a defining moment in the history of America's civil-rights movement. Now, acclaimed filmmaker Spike Lee tells the full story of the bombing, through heart-wrenching testimonials from surviving members of the victims' families, insights from Bill Cosby, Walter Cronkite, Andrew Young, Coretta Scott King and many others, and a rare and revealing interview with former Alabama Governor George Wallace.
