Raised in isolation, the children of Sunderland face an overwhelming choice. They can attend school to learn the teachings of The Angel, an extraterrestrial being that arrived in Sunderland 10 years ago, and "Evolve" like their parents who were turned into mindless zombies, or they can “Fall”…living their lives in the wasteland at the edge of the community where their rebellions are tolerated. Like some of the other children David has already decided to Fall when the time comes, but he has his own reasons. The Angel killed David's mother. When a fallen trespasses into the heart of town and shoots David, The Angel intervenes, offering David a final malevolent chance at salvation.
