After years of relentless bullying, teenager Joseph Harris is close to despair. When he is assaulted at school on his sixteenth birthday, both his teachers and parents ignore his pleas for help. Seeing no other choice, he takes his own life to end his misery. Expecting to be damned to Purgatory, Joe awakens in Limbo where he is offered the chance of redemption. He is tasked to save the soul of an innocent child, one at the centre of a battle between God and the Devil. At stake, the souls of all the Lost Youth, the bullied children who have taken their own lives and are damned to Hell. As the child grows, the Forces of Hell send their top General to torment the boy, to drive him to follow Joe's fate, while Joe combats the threat with his own growing power and understanding of the Ethereal World. Finding allies and enemies in unusual forms, Joe struggles to keep the child, Adam, from falling into the hands of Satan and his Demon host as they seek to capture the Soul Key, which is blocking their entry back into Heaven. As Angels, Fallen Ones and Demons gather, the fulfillment of an ancient prophecy lead the celestial forces to battle "For The Lost Soul."
