The award-winning HBO documentary series Paradise Lost: The Child Murders at Robin Hood Hills (1996) and Paradise Lost 2: Revelations (2000) spawned a worldwide movement to free the West Memphis 3 for wrongful murder convictions. Paradise Lost 3: Purgatory tells the entire story, from the arrests in 1993 to the growing movement, through the entire appeals process and the uncovering of new evidence, concluding with their release. We have the second trailer, which you can check out below.
