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.
