Irene Trent's sleep-talking convinces her blind husband, Howard, that she is having an affair with another man. He suspects his attorney, Barry Morland, who denies the charge. Irene reveals to Barry that she repeatedly dreams of an unknown lover. After a quarrel with Howard, Irene leaves the house; shortly thereafter, Howard is killed in an explosion in his laboratory. Irene's dreams continue. She is visited repeatedly by her lover, who transports her to a chapel peopled by wax dummies, where a bizarre wedding ceremony is enacted. Irene enlists Barry's aid, and the lawyer reveals that Howard had hired George Fuller, a private detective, to spy on her. Fuller is later identified as the dream lover. Joyce, a new beautician in Irene's shop, is murdered by a man resembling Howard. Barry then informs Irene that Howard is alive and has attempted to slay him. In Howard's laboratory, however, Barry removes the mask with which he had impersonated the dead man. He further reveals that he had murdered Howard, having first named himself the blind man's beneficiary. As Barry attempts to stab Irene, he is shot and wounded by George, who informs Irene that he is the husband of the dead Joyce. Although George menaces Irene, Barry revives. During a final struggle, Barry and George fall through a gaping hole in the laboratory floor. Irene is now safe.
