Chicago is gripped by an Axe Murderer. The streets are empty at night as there has been six murders and six people have been caught, but they are lunatics. Only one person has lived to tell about it, Edwina, who is as dumb as a brick. If it were not for Oliver, she would be number seven. When there is a second attempt on Edwina, Oliver figures that the crimes are not random and that someone is hypnotizing these people to do his bidding, but the police and Edwina are skeptical.
