The story begins in the wake of the four lead-in limited series, with Superman, Wonder Woman, and Batman feuding, the JLA Watchtower destroyed, and the heroes of the world all facing a variety of menaces. Over this backdrop, Kal-L (the Earth-Two Superman), along with Earth-Two's Lois Lane, Earth-Three's Alexander Luthor, and Superboy-Prime escape from the pocket universe where they had initially fled to at the end of "Crisis on Infinite Earths". Kal-L seeks out his cousin, Power Girl, also a survivor of Earth-Two. Believing Lois' health will improve on her native world, he hopes to replace the current Earth with Earth-Two, which he considers perfect.
