Synopsis:
Superboy investigates the disappearance of a missing museum curator who has gone in search of a fallen meteor. Superboy discovers the professor in the dense jungle held captive by some knights. He learns that a Wizard City exists nearby, and the professor's guide Vedders has gone there.

Superboy locates the city which was contained in the meteor. It is a Kryptonian city which has fallen to Earth after the planet's destruction. The Kryptonite prevents Superboy from approaching, so the professor dresses as Superman to stop Vedders from using the weapons of the city.

After defeating Vedders, Superboy and the professor return to civilization. The professor's young son Jimmy is grateful for his father's return. Jimmy idolizes Superboy and eventually grows up to be Jimmy Olsen, Superman's pal.
