Batman (serial)

The Batman/Bruce Wayne (Lewis Wilson), and his ward, Robin/Dick Grayson (Douglas Croft), secret government agents following the Japanese attack on Pearl Harbor, become aware of a Japanese sabotage ring operating in Gotham City. Bruce's girlfriend Linda Page (Shirley Patterson) asks for his help in finding her uncle, Martin Warren (Gus Glassmire), who was abducted by the ring after he was released from prison. Dr. Tito Daka (J. Carrol Naish), the Japanese leader of the ring, plans to steal the city's radium supply to power his invention, a hand-held ray gun that can dissolve anything hit by its powerful beam. He forces from Warren the location of the vault where the radium is stored. Daka sends his American henchmen, along with a zombie that he controls by microphone via an electronic brain implant, to steal the precious metal. Batman discovers the plot and eventually routs the gang after a terrific battle.
