Synopsis:
Luthor has invented a belt which reduces him and his gang to tiny size. Using the belts, Luthor sets up a trap for Superman. Unknown to Superman, he brings Luthor into the Fortress of Solitude inside a machine Luthor has built to use as a trojan horse.

Once inside the Fortress, Luthor infilitrates the bottled city of Kandor. Superman follows him inside, but without his powers in the Kandorian City, he is captured by Luthor’s gang. Luthor then forces the citizens of Kandor to give him their advanced weapons.

Following a lead of their own, Batman and Robin arrive at the Fortress and enter Kandor. They rescue Superman and take on Luthor with him. Luthor is victorious and leaves Kandor. However, the heroes are still alive and follow him outside. Superman and Batman remain tiny in size because the belts they used were broken, but Superman’s powers return. Together they defeat Luthor and his men.
