Dr. Alex Zorka, a mad scientist, conducts bizarre experiments in his secret laboratory, assisted by his henchman Monk, an ex-convict. A devisualizer belt that renders its wearer invisible and a frightening eight-foot tall robot are among Zorkas inventions, which include small mechanical spiders that induce a state of suspended animation when they explode. The secret of Zorkas scientific power is a weird meteorite fragment that he has recovered from Africa; it contains almost unlimited energy. Capt Bob West of millitary intelligence is assigned to investigate Zorkas activites. Also, a group of foreign spies is attempting to learn his secrets, as well as a nosy (and pretty) newspaper reporter.
