A randy stud, a Kentucky Derby winner, sires a successor on the sly and creates all sorts of problems for his owner in this drama. The mare carrying the heir belongs to an impoverished nobleman and his beautiful granddaughter whom the stud's owner despises. Fortunately, the stable-owner's son, who loves the granddaughter, helps them train the promising young colt for the Big Race. When Derby day finally arrives, her horse is slated to run against one belonging to her rival. ~ Sandra Brennan, Rovi
