Chicago is gripped by fear as an axe murderer stalks its streets. With six murders, six lunatics caught, and the city empty at night, terror reigns. Edwina, the only surviving witness, is considered dim-witted and barely escapes death thanks to Oliver. When there's a second attempt on Edwina's life, Oliver suspects a sinister plot—someone may be hypnotizing people to kill on command. Despite skepticism from the police and Edwina herself, Oliver races against time to uncover the truth. Cast: - Lew Ayres as Oliver Duffy - Laraine Day as Edwina Brown - Basil Rathbone as Dr. H.
