A thrilling 15 chapter serial of a mechanical monster gone mad! 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.
