Andy Sommerville seems no different from others in his rural Virginia community, but what sets him apart is that his best friend is an angel. The angel is God's answer to a childhood prayer Andy offered to a twinkling star that his deceased mother once called "the door to heaven." The first angelic proclamation instructs Andy to find the wooden keepsake box in his grandparents' attic. Over the years, he directs Andy to fill it with apparently meaningless objects from 12 people with whom Andy randomly crosses paths. Andy's world is turned upside down when a brutal attack leaves Andy burned and the boy he loved as a son dead.
