Sixteen-year-old Ryan Matthews had always been the 'cool' kid in school, but being 'cool' doesn't get him a free pass into Heaven. Marty, Heaven's gatekeeper, refuses to let him in until Ryan returns to Earth to make a difference in someone's life. Sounds easy enough. That is, until he learns that 'someone' is Zachary Adams, his old classmate and the world's biggest geek. Convincing Zachary that he's his angel isn't an easy task. Especially since Ryan hadn't exactly been nice to him in school. But Ryan is determined to see this assignment through, especially when he begins to see life through the eyes of a geek. To make up for the way he'd treated Zachary, Ryan is not only going to teach him how to fit in. He's going to help him win the heart of Kristen Williams, a girl Ryan used to be close friends with, the same girl Zachary has a thing for. Will Ryan finally get those white wings he's been working toward? Or will he end up on the wrong side of those Pearly Gates a hopelessly fallen angel?
