Once-incarcerated Marcus Cowans is trying to turn over a new leaf with the support of his loving family. Upon discovering that one of his brothers may have been involved in a horrific crime, Marcus grapples with the limits of brotherhood and loyalty. He and his family, increasingly weary of the justice system’s failings, end up in the crosshairs of a seasoned but jaded detective.
