When a hypnotist named Norman Osgood mesmerizes a man named Harrison Kirke without his consent, Kirke threatens to kill him. Afraid for his life, Osgood hypnotizes another man named George Clayton and tells him he must murder Mr. Kirke one hour before the arrival of the dawn. Kirke is found murdered the next day, and Clayton starts to believe he was the murderer.
