Dr. Mabuse and his accomplices steal all kinds of attributes from a National Research Institute (including female staff members) in order to complete his own evil mind-control ray. Dr. Mabuse has this impressive and horribly scarred man-monster that kills for him while the entire police force desperately tries to catch him.
