Acts of violence tore Charlie's family away from him when he was ten. At age sixteen, Charlie's life seems to come together again when he finds a father figure in a man named Sam, but on his eighteenth birthday his world is turned upside down again. In a bizarre ceremony hosted by Sam and a mysterious flock, Charlie is wedded to Charlotte, a girl he just met. As the two start their new life together, a freak accident takes Charlotte away from Charlie and frames him as the culprit for a crime he didn't commit. As punishment, the flock's leader gives Charlie the task of watching over the Passage, a portal where evil crosses back into the land of the living. Trapped and alone, Charlie will risk everything to escape the flock's clutches. He finds help along the way...but will they be able to help Charlie save his own soul?
