Synopsis:
The Nazis hold a secret meeting to discuss Superboy, who is an obstacle to their success. They send saboteurs to Smallville. The saboteurs threaten to destroy the town if Superboy doesn't leave Earth. He reluctantly meets their demands after the townspeople turn against him. Pa Kent then discovers the Nazis planting explosives in the town's sewer system. He fails to stop them and is shot.

From space, Superboy sees Jonathan's body. He stops the Nazis and floods the sewer system to disable the bombs. After the town is safe, he returns home where the real Jonathan Kent is. The man that was shot was really a Jonathan Kent robot created by Superboy himself.
