His investigation leads him to a man who lived in 1958 named Matthew Wakefield (Josh Lucas) and his innocent son, John. The striking similarities in the cases pushes Adkins' obsession over the top. Barely holding onto his sanity and bound by redemption, Adkins unravels the unspeakable truth behind what happened to his son.
