Synopsis:
While retrieving a space jewel for his mother, Superboy is captured by a space-probe. He is taken back to Argo City which is currently floating in a red sun solar system. Superboy was hit in the head and has amnesia. He is taken in by Zor-El, though neither one knows that they are related. Superboy befriends Zor-El's young daughter Kara and gives her the space jewel that he intended to give to Martha Kent.

Zor-El eventually completes his project to build engines which can transport Argo City to another solar system. The city soon enters a new system inhabited by hostile alien life forms. The Kryptonians agree to leave the system, but the aliens demand that someone remain behind. Superboy volunteers.

The aliens then erase the memory of Superboy from the minds of the people in Argo City. Zor-El then pilots the city to a different solar system. Superboy regains his powers and is able to escape from the aliens, but he has no memory of his time in Argo City.

Years later Kara, now Supergirl, shows the space jewel she still possesses to Superman. She can't remember where the jewel came from. Superman remembers the jewel too, but has no idea how it came into Kara's possession.
