Sisters Yancsi and Roszika Dolly are loved by Jack Hobson and Tom Hylan respectively, but the twins refuse to marry until they are as wealthy as their prospective husbands. Accordingly they agree, in exchange for a million dollars, to aid a celebrated psychologist who is developing a cure for an ailing maharajah. The maharajah inexplicably detests his bride, a beautiful princess, and the Dolly sisters are sent to his New York palace to learn the cause of his odd behavior. They soon discover that the maharajah has been hypnotized by his uncle, the Rajah Ismael, but the spell is broken when, after a series of dangerous adventures, one of the twins obtains a ring from the maharajah and gives it to the princess. As the maharajah takes his wife in his arms, the Dolly sisters return home with their million and prepare to marry their sweethearts.
