Plot
Lois accidentally releases from Kandor the criminal Zak-Kul, who traps Superman in Kandor and takes over his life. Lois marries Zak-Kul thinking him Kal-El, but he tries to kill Lois because she keeps asking him Kal-El's secret id. Kal-El, trapped inside the "Krypton City," uses one of the three remaining specks of Illium-349 to shrink himself even smaller and slip between the atoms of Krypton City's jar, then uses the second speck to enlarge both himself and the third speck. Zak-Kul meanwhile futilely attempts to hide from Superman by disguising himself as a mild-mannered reporter.
