The new trailer for Devil's Knot has been released and, given the subject matter, it can definitely be difficult to watch.
Based on Mara Leveritt's best-selling book of the same name, the film follows the true story of three teenagers—Damien Echols, Jason Baldwin and Jessie Misskelley Jr.—who became known as the West Memphis Three after they were accused and convicted of killing three young boys in Arkansas in 1993.
The movie, however, puts the spotlight on the grieving mother (played by Reese Witherspoon) of one of the murdered boys, as well as a private investigator (portrayed by Colin Firth) who is not convinced the convicted teens are guilty of the crime.
In 2011, the Memphis Three were eventually released. Peter Jackson, Eddie Vedder, Natalie Maines and Johnny Depp were just some of the famous faces who believed the trio was wrongly convicted.
"Johnny has been with us every single step of the way since I got out," Echols told E! News after being given his freedom. "We've known to love him dearly. He's become like a brother to me."
Directed by Atom Egoyan, Devil's Knot also stars Amy Ryan, Mireille Enos, Dane DeHaan and Stephen Moyer.
It hits theaters on May 9.
