Batman and Robin encounter a magnetically-powered villain, the Zebra-Man, but a charge from the machine which gave Zebra-Man his powers turns Batman into a "Zebra-Batman" who repels all solid matter, and without a belt like Zebra-Man's to neutralize the repelling force, he cannot regulate his powers. With Robin's help, Batman finds a way to use his unwanted magnetic force to capture the Zebra Man and after the criminal is captured, Batman uses the crook's magnetic belt in order to neutralize his magnetic force and return to his normal state.
