We follow the training and adventures of a team of young federal anti-gangster agents, Mal Stevens, Van Rensseler, and Tex Logan. After foiling a kidnap attempt on socialite Eleanor Spencer (an old flame of Van's), Mal falls for her; but they're at odds over her belief in the innocence of her chauffeur Joe Keefer (whom Mal knows was involved) and her young brother Buddy's desire to join the federal agents. This conflict climaxes with the pursuit of an Ohio bank-robbing gang.
