Dr. Fernandez, a physician, is believed by Mendoza, the military governor of Mexico, to possess hypnotic powers. Mendoza is in love with Dr. Fernandez’s daughter, Zora. When Zora displays no love for him, Mendoza assumes that the father is responsible for the failure of his suit. So great becomes the hatred between the two that when a faction of insurrectionists, arises the doctor places himself at its head and leads it against the Government. Dr. Fernandez is killed in battle. In the meantime, Dolores, the daughter of the Governor is suffering with somnambulism. While she is anxious to be cured, she dislikes to inform her father or her lover that she is so afflicted. Finally her old nurse makes the fact known to Zora, who possesses the hypnotic power that was her father’s. Dolores submits to treatment at the hands of Zora and is cured. At the time that Zora brings about the cure of Dolores, the former does not know that Dolores is engaged to be married to Riques, Zora’s sweetheart. When she does learn that the wedding day is set, she goes into a rage, and contrives to get into the palace in the night and hypnotizes Dolores. Shortly thereafter Zora is denounced as a witch and is carried away by an angry mob to be burned at the stake. Just before the torch is applied, the old nurse makes known to the Governor that his daughter has the habit of walking in her sleep and that she is in a trance from which she cannot be aroused. Also the old nurse informs the Governor that the only person who can cure his daughter is Zora. At the last instant, the Governor stays the burning of Zora and promises her freedom if she will bring Dolores from her lethargic state. Zora, believing that the Governor is acting in good faith, goes to the palace and wakens the girl. When Dolores is found to be safe, the Governor goes back on his word and commits Zora to prison. She escapes, however, and Riques, who realizes that he loves Zora more than Dolores, runs away with her. The two are captured after a fight and in the end Zora is put to death.
