Meet the folks of Humble County, Georgia. There's Jimmy Wiggins, who believes cars are evolving into fish; Daisy, whose outlaw diner caters to three dry counties; Ruby Mulvaney, falling apart piece by piece; Mr. Thigpen, a foot-washing Baptist out to save your soul, like it or not; and Earl Mulvaney, a high school dropout and mechanical genius. When the girl next door breaks Earl's heart, everybody rallies to help him. He finds purpose in a fabulous quest: by saving the leftover parts from maintaining Jimmy Wiggins's classic '53 Corvette, he'll build a whole new car and leave the original behind. And just maybe, he'll drive away with the girl.
