Following his fruitless search for answers to the mystery of the body in his tomb, Superman returns to Metropolis...where no one believes he's the real thing.
Believing Mr. Mxyzptlk is behind the duplicate of Superman’s dead body left in Centennial Park, Superman sneaks into S.T.A.R. Labs to try to prove that the corpse is one of Mxyzptlk’s tricks. Guards at S.T.A.R. Labs find the Man of Steel trespassing, and call in the Metropolis S.C.U. Worried about Superman’s erratic behavior since the arrival of the corpse, and unsure whether Superman is the real Superman, Maggie Sawyer and Dan Turpin show up in the S.C.U.’s new giant robotic armor. Superman, believing this to all be a game created by Mxyzptlk, makes short work of the armor. Losing his sanity, Superman almost punches Maggie Sawyer to prove she is just a Mxyzptlk-created illusion. Mxyzptlk shows up, saying that he is not the culprit. Shocked at having almost killed Maggie, Superman flees. Meanwhile, a serial killer names Ramsey Murdoch has killed a telemarketer, and the real culprit, Brainiac, is escaping his prison on New Genesis.
