Captain Marion Scott is nearly killed while hitchhiking by runaway socialite Wilhelmina "Willy" Pierce Hammond when her car blows a tire while attempting to avoid him. Marion agrees to change her tire if Willy agrees to give him a ride into the town of Plainfield. The two soon run out of gas, however, and while Marion walks to the nearest gas station, Willy goes through his luggage, where she discovers his military uniform. Just outside of town, they are arrested for driving a stolen car, as Willy had "borrowed" the car from her politician fiancé, Alvin Baily III. Upon their release from jail, Willy tells Marion that she is the wealthy Hammond family's secretary, and offers to let him stay at the estate while the family is out of town. The two are arrested once again for breaking into the mansion, but this time Willy is recognized by the reporters at the police station. Back at the Hammond estate, Willy admits to Marion her suspicions that he is a deserter, only to learn that he is a wounded veteran who has been discharged from the military for medical reasons. Marion then tells Willy that he is an orphan who had never been to Plainfield before, but now considers it his home town, having been told all about it by one of his deceased comrades. Learning that her family and Alvin are returning to Plainfield the next day, Willy hires Marion as the new chauffeur, though her interest in him is more personal than professional. Despite the objections of her family, Willy confesses her love for Marion and attempts to break her engagement to Alvin. The family and Alvin, however, decide to go on with the planned wedding the next day, moving its locale from New York City to Plainfield. After Alvin fails in his attempts to throw Marion off the estate, Willy's mother offers to pay Marion to leave, thinking that he is a fortune hunter. That night, Marion drives off with Willy and proposes to her, but she refuses out of loyalty to her family. The family, however, has called for the police, believing that Marion is both a kidnapper and a deserter. The next morning, the townspeople of Plainfield arrive at the Hammond estate, not for the wedding of Willy and Alvin, but for the wedding of Willy and Marion, who they have discovered is a bona fide war hero. Willy then stands up to her family and is finally united with Marion.
