One day, one of his letters gets accidentally mailed and Julia receives it. When the letter says that he is a fraternity man and a big track star, Julia rushes right over to see him. But John is neither and Spike, Julia's boyfriend, is a track star at a nearby College. John does not want to enter the track meet so Julia tries to use psychology on him. That and a good wrestling hold makes John timidly agree to enter the race, but Spike still scares him.
