Synopsis: Trok and Graz, two members of the Superman Revenge Squad, hit Clark Kent with a ray made by a machine constructed with Kryptonian components. The ray causes Clark Kent to become a coward, but, in his Superman guise, he is his usual courageous self. Superman gets around the problem for a while by adopting the new secret identity of Brad Dexter. However, Supergirl snaps him out of his fear-spell by secretly having him wear a non-invulnerable Superman costume over his Clark Kent clothes. The costume is burned off by friction, and, when Superman sees he is doing a super-feat while in his Clark Kent identity, his fear fades. Superman then throws Trox and Graz's spacecraft into the midst of a space police parade, and the two villains are nabbed.
