After his father's sudden death, Dick Browning learns that three financiers swindled Mr. Browning of his money. Because his mother is destitute, Dick fences the only remaining jewel in his father's estate, but when she dies, he joins a gang of crooks, vowing revenge on the financiers. Dressed in feminine attire and known as Mary Brown, Dick robs two of the men. In the meantime, he has fallen in love with Betty, a woman who was lured to the crooks' lair by one of his cronies.
