Dr. Muller, a friend to all, finds pleasure in turning the goodness in people to evil ends. He meets Marie Matin and her fiancée, Georges Roben, while viewing a new painting, "The Martyr--Truth Crucified by Evil." Marie declares that the picture was wrong--evil could never triumph over truth--and though Muller says he agrees with her, he plots to prove otherwise.
