When the Civil War ended in 1865, more than four million slaves were set free. Over 70 years later, the memories of some 2,000 slave-era survivors were transcribed and preserved by the Library of Congress. These first-person anecdotes, ranging from the brutal to the bittersweet, have been brought to vivid life in this unique HBO documentary special, featuring the on-camera voices of over a dozen top African-American actors.
