Synopsis:
A costumed youth called Ultra Boy secretly arrives in Smallville with his adult mentor, Marla, intent upon discovering Superboy's secret identity. Ultra Boy at first suspects that Pete Ross is the Boy of Steel, but then correctly deduces that Clark Kent is actually Superboy.

When Pete accidentally becomes locked in a bank vault, Ultra Boy’s power of penetra-vision which, unlike Superboy’s super-vision, can melt and see through lead, enables him to assist Superboy in rescuing Pete. He then reveals that he is a time-traveler from the future planet Rimbor and an applicant for membership in the Legion of Super-Heores, who have assigned him the task of unmasking Superboy as an initiation test. Having completed the test, he and Marla, actually the Legion’s Senior Advisor, return to the future.
