A dying stranger abandons a baby girl in a gypsy camp, with a note explaining that on her eighteenth birthday, she is to inherit a Virginia estate. The gypsy chief, aware of the girl's value, instructs Sabia, the tribe's matron, to dress and rear her as a boy. Years later, while the tribe is traveling in Virginia, Vosho, the chief's son, discovers the true sex of the girl, now called Firefly, and demands to marry her. Forced into marriage, Firefly flees from the camp on her wedding night and meets up with Donald McDonald, a local newspaper editor. Donald, thinking that Firefly is a boy, hires her as an errand runner and she soon falls secretly in love with him. Eventually, she unites with her uncle and lives happily on his estate until Vosho shows up to claim her. After a hard fight, Donald rescues Firefly and jails Vosho, who is later freed by Firefly's jealous cousin.
