Synopsis:
Superman issues a statement to the public that a special vault with valuable contents will open when he dies. The vault is made of indestructible Supermanium and is kept under heavy guard. Luthor, provoked by articles in the Daily Planet, renews his efforts to kill the Man of Steel, who exhibits signs that he is weakened.

Luthor steals the vault uses a modified version of Brainiac's shrink ray. He then uses robots with Kryptonite inside to kill Superman. Thinking that he has finally succeeded in his goal, Luthor waits for the vault to open. When it doesn't, he uses every means necessary to break into the vault.

Luthor finally succeeds in opening the vault and discovers Superman inside. The Man of Steel apprehends Luthor, then explains that Mordru had magically imprisoned him in the vault. Supergirl and the adult Brainiac 5 then tricked Luthor into opening it by having the Legionnaire pose as the Man of Steel. Angry at being tricked, Luthor is nevertheless sent back to prison vowing vengeance.
