An authoress writes a steaming sex-novel and proceeds to live out her heroine's adventures.

Lucky Jackson arrives in Las Vegas with his car literally in tow ready for the first Grand Prix — once he has the money for an engine. He gets the cash easily enough but mislays it when the pretty pool manageress takes his mind off things. It seems he'll lose both race and girl, problems complicated by rivalry from womanizing fellow racer Elmo Mancini.
