Dr. Leo Quintum and his team are exploring the Sun when they are sabotaged by a booby-trapped genetically-enhanced clone, turned into a time-bomb by Lex Luthor. Superman stops the clone but in doing so receives an overdose of solar radiation. Though the radiation is slowly killing him, it does give Superman new powers. Luthor, having orchestrated the death of Superman while under the employment of General Sam Lane, is arrested by the military thanks to Clark Kent's article and sentenced to death by a Metropolis tribunal. Superman asks Dr. Quintim to keep news of his impending death secret from the public. Wanting to spend as much of his remaining time with Lois Lane, Superman reveals to her that he is Clark Kent. Lois doubts his revelation because she had been unable to prove Superman's \93Kent\94 identity herself. Superman takes her to the Fortress of Solitude. During this visit, Superman's secretive behavior and her indirect exposure to alien chemicals heightens Lois' paranoia.
