Peter Mason, a salesman in a sporting goods store, calls his boss Frome's attention to the need for more advertising. Frome points out that they have a contract with steeplechase jockey Peter Randall to represent them, but he is in Australia. Franklin Dexter, a fellow salesman, proposes that Peter pose as Randall to represent the store at the Maryland Steeplechase. Although he cannot ride, Peter reluctantly agrees. At the hotel, Ellen Parker and her aunt, Cora Withering, introduce themselves to Peter and invite him to a party at their home. Two racetrack habituées, Maxie and Droopy, also introduce themselves to Peter. They have seen Jeepers Creepers, an unmanagable horse who will only respond to the song Jeepers Creepers. They want to bet on the horse and think Peter will be able to manage him. Peter refuses, protesting that he cannot really ride, but at the Witherings' party, he accidentally lands on Jeepers Creepers and rides him. Ellen is impressed and as Peter is in love with her, he agrees to ride her horse, Lady Ellen, in the race. Maxie and Droopy, however, force Peter into riding Jeepers Creepers. Peter arranges for the horse's trainer, Gabe, to follow the race with a band playing his song. Despite the fact that the horse leaves the track to follow the band, Peter wins the race. Frome promotes Peter, who makes up with Ellen. Only Dopey is unhappy because he bet on another horse.
