Synopsis by Hal Erickson
This 104th and final episode of The Adventures of Superman not only stars George Reeves as the title character, but was directed by Reeves as well. Eccentric inventor Professor Pepperwinkle (Phillips Tead) has created a machine which he claims can produce gold from ordinary metal. And that's not all: Pepperwinkle has also developed a new strain of positive and negative Kryptonite. Whereas negative Kryptonite has the capacity to sap Superman of his strength, positive Kryptonite restores that strength--and also transforms reporters Lois (Noel Neill) and Jimmy (Jack Larson) into superpowered superheroes themselves! Unfortunately, once the inevitable villains arrive to steal the gold-manufacturing apparatus, "Super Lois" and "Super Jimmy" literally awaken to the discovery that they're still plain, ordinary mortals.
