A villainous doctor murders one of his patients, a soldier, and then proceeds to make life a misery to the latter's betrothed, in whose favor his will, had been made. With the object of securing possession of the girl's money, he again and again presses her to marry him, and she is unable to invoke the intervention of the law because of the fact that she was the unwitting medium through which the death of her lover was brought about. Then, one morning the doctor is found dead in her garden. Known to have repeatedly quarrelled with him, she, naturally, is arrested and charged with his murder. The case against her, notwithstanding her protestations of innocence, is extremely black, and it seems that nothing can prevent her from going to the gallows. She confides to her lawyer, however, that she was with the victim a moment before he died, and that she heard him mention the word "Whispering."
