Dr. Alex Zorka is the creator of several wondrous devices that a former partner asks him to contribute to the U. S. Government, but he decides to use for his own benefit and ultimately world domination. With foreign spies desperate to get their hands on Dr. Zorka's inventions, the U.S. Government sends in Captain Bob West of the Military Intelligence Department to find the doctor, who has gone into hiding after the death of his wife, and stop both him and the spies before either can use the devices for their evil purposes.
