At the Bainbridge Research Foundation, Professor Franklin Arnold displays his creation, a robot called the Metalogen Man, to Professor Ernst and three other colleagues. Shortly afterward, the three associates are killed by Thor, a huge ape trained by Ernst. Professor Arnold, his daughter Babs and Ken Morgan, a representative of the company for whom the robot was made, find the Metalogen Man has been stolen. Their thrilling 15-chapter search for Thor, the robot (Played by Ray Corrigan) and Ernst leads to a series of cliff-hanging adventures as Ernst strives to gain control of the robot and the supply of metalogen needed for its production.
