A masked attacker shoots up an apartment in Bucyrus, Ohio, leaving three dead and two young children clinging to life. After witnesses report seeing a "large black man" near the scene, police close in on Kevin Keith, a local drug dealer who was recently busted based on information offered by a snitch. It was the snitch's family that was murdered, leading prosecutors to argue Kevin's motive was revenge. Despite the lack of physical evidence, Kevin has spent 25 years locked up - but a young public defender believes long-hidden case records will shed new light on the Bucyrus murders and clear Kevin's name.
