Based on the true crime book, Devil's Knot: The True Story of the West Memphis Three by Mara Leveritt, DEVIL'S KNOT tells the compelling story of three teenagers accused of the brutal 1993 murder of three 8-year old boys in Memphis, Ark. - two of them sentenced to life imprisonment and one to death. The film explores the lives of deeply misunderstood outsiders, their families and communities, and their darkest fantasies. The conviction of the West Memphis Three - Damien Echols, Jesse Misskelley, Jr., and Jason Baldwin - riled the American justice system, shocked a tightly knit religious town and outraged the nation.

The compelling tale of the West Memphis Three also inspired a trilogy of HBO documentaries known as Paradise Lost, which chronicled the arrest, 18-year imprisonment and eventual release of the three men. The final film in the series received a 2012 Primetime Emmy Award for Exceptional Merit in Documentary Filmmaking and a 2012 Academy Award nomination for Best Documentary.
