John Light: John Light is one of the most dangerous inmates in Arizona's State Penitentiary. But he has stunned both guards and inmates alike, by accepting Christ in a prison bible study. Upon his release, he's anxious to share his new faith with the outside world. However, looking more like a thug than a theologian, the outside world is terrified of him. His only allies are his meek and mild Christian mentor, Matt Garrett and his no nonsense parole officer.
