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 the civil-rights movement. Spike Lee re-examines the full story of the bombing, including a revealing interview with former Alabama Governor George Wallace.

Renowned Black writer James Baldwin retraces his time in the South during the Civil Rights Movement, reflecting with his trademark brilliance and insight on the passage of more than two decades. From Selma and Birmingham and Atlanta; to the battleground beaches of St. Augustine, Florida, with Chinua Achebe; and back north for a visit to Newark with Amiri Baraka, Baldwin lays bare the fiction of progress in post–Civil Rights America, wondering “what happened to the children” and those 'who did not die, but whose lives were smashed on Freedom Road'.

Constructed from a wealth of archival footage, the documentary follows Dr. Martin Luther King, Jr. from 1955 to 1968, in his rise from regional activist to world-renowned leader of the Civil Rights movement. Rare footage of King's speeches, protests, and arrests are interspersed with scenes of other high-profile supporters and opponents of the cause, punctuated by heartfelt testimonials by some of Hollywood's biggest stars.
