Synopsis:
Professor Potter invents a machine that exchanges personalities. Jimmy and Clark are the first subjects, but the machine doesn’t work. However, Jimmy thinks it did because now Clark is acting brave. Refusing to believe he has been turned into a coward, Jimmy recklessly endangers himself. Superman’s intervention prevents Jimmy from harming himself and convinces Jimmy that he is now a coward. Jimmy and Clark then return to Potter’s lab and reverse the process.
