Superman's Justice League gathers more captives than converts, and his prison (nicknamed "the Gulag") is filled to capacity almost as soon as it is built. Superman works to persuade the inmates that their methods are wrong-headed and dangerous, but his entreaties fall upon deaf ears. With hostile heroes and villains locked up together, pressure builds. Meanwhile, Superman learns that Wonder Woman's ardent militant stance may be influenced by her recent exile from Paradise Island: in the eyes of the Amazons, her mission to bring peace to the outside world has failed, and she has thus been stripped of her royalty. Batman and his Outsiders seem to enter into an alliance with the MLF as a united front against the Justice League. Luthor plans to exacerbate the conflict between the League and the inmates of the Gulag; the ensuing chaos will afford Luthor an opportunity to seize power. Batman uses the Martian Manhunter to discover that an adult Billy Batson is under Luthor's control. Batson, as Captain Marvel, is the only metahuman capable of matching Superman's power. When the Gulag's inmates riot and kill Captain Comet, Luthor unwittingly reveals to Batman he intends to use the brainwashed Batson to break open the Gulag. Batman's forces ambush Luthor and his conspirators, but they are unable to restrain Batson, who transforms into Marvel and flies off. While Wonder Woman leads the Justice League to the superhuman prison riot, Superman confronts Batman. Batman tries to justify inaction, saying the world would be better off if all the metahumans destroyed each other. Superman points out that if all human life is sacred, then logically that includes superhuman life. Superman knows that Batman will act, because his entire crimefighting life is based upon the desire to prevent the loss of human life.
