Paradise Lost 3: Purgatory (2012) on Netflix

In 1993, a horrific triple child murder was discovered in West Memphis, Arkansas, but the reaction to it precipitated a horror of its own. This film follows up on the story of the three boys, called the West Memphis Three, who were convicted for this crime with questionable evidence. For years, the boys' fate sparked a mass movement striving to prove their innocence while the state is equally determined to avoid admitting it could have been wrong. Through the swirl of new evidence and suspects, the Three tell their own tale about enduring this injustice against the opinions of the victim's families in a debate that eventually came to an inadequate resolution.
