"Wild Cat" Betsey Dawley, whose father "Handsome Harry" was disowned by the proud Dawley family of Greenburgh, Kentucky, meets and thoroughly charms her snobbish cousin Virginia's fiance John Davidson at a picnic. At the start of the Civil War, John becomes a Union officer, while Betsey and her father staunchly defend the South. When Confederate Colonel Morgan, the leader of the intrepid band known as "Morgan's Men," commissions a young horseman to deliver an important message to the Dawley mansion, the rider is shot and Betsey takes his place, breaking through the lines and successfully accomplishing the mission. Later, she again demonstrates her courage by rescuing her wounded father from Davidson's men, but in the process, she is caught by a Northern spy. Davidson saves her, and after the war, they are united.
