Synopsis:
While visiting Superman’s Fortress of Solitude, Lois Lane accidently knocks over the bottled city of Kandor allowing a criminal, Zak-Kul, to escape. Zak-Kul enlarges himself using a rare element known as Illium-349. He then uses a machine to make himself identical to Superman. When the real Superman returns Lois shrinks the wrong one, and he is sent to Kandor.

Zak-Kul takes over Superman’s life in Metropolis and even marries Lois Lane. Superman finds just enough Illium-349 in Zak-Kul’s Kandorian lab to enlarge himself. He rescues Lois, who Zak-Kul was trying to kill. Then Superman locates the villain and sends him back to Kandor.
