Synopsis:
Lex Luthor has returned with a formula that makes his skin give off Kryptonite radiation. Superman is forced into hiding as Luthor chases after him. The Man of Steel constructs a lead suit that allows him to approach Luthor and stop him. Using a tiny oribiting satellite, Luthor turns all lead on Earth into glass.

Without lead for protection, Superman flees to the moon where he constructs a second lead suit. He is able to disable the satellite before returning to Earth. Luthor destroys the lead suit, but Superman appears unaffected by Kryptonite now. Fearing the green glow will give away his presence, Luthor drinks the antidote. Superman then captures him. The Kryptonite was affecting him, but he faked being unaffected.
