After a violent and tragic death, nihilistic career criminal Kevin Princeton ascends into Heaven. Throughout his journey for redemption, discovery and spiritual awakening, he has to come in terms with his new life as a guardian angel called an Apostle. But when he is caught in the conflict of the war-torn nature of the afterlife, he has to make a choice to either find a place in his new life to save Heaven from invasive forces of Hell ...or to hold onto a life he couldn't have as a human.
