In 1993, three 8-year-old boys were brutally murdered in West Memphis, Arkansas. Three teenagers were convicted of the crime and sentenced to life in prison. But what if they didn't do it? This documentary follows the journey of the West Memphis Three, who spent nearly 20 years in prison before new DNA evidence suggested they may be innocent. Through interviews with the convicted men, their families, and those involved in the original investigation, the filmmakers uncover shocking new truths about the case and raise questions about justice and innocence. Is it possible for the justice system to make a mistake? And what happens when the truth finally comes to light?
