When sixteen-year-old Luke's book, Hallelujah, becomes a national best seller, his publisher sends him on a cross-country tour with his unpredictable older brother, Matt, as chauffeur. But when Matt offers to drive Luke's ex-crush, Fran, across the country too, things get a little crazy. Luke thinks he's enlightened, but he really needs to loosen up if he's going to discover what it truly means to have faith, and do what it takes to get the girl he loves.
