Kenan Kong , the new Super-Man of China, has been taken, Kal-L, the Red Son Superman on Earth-30, is gone. Sunshine Superman, the mystical protector of the Dreamworld, has vanished without a trace. Someone - or something - is collecting Supermen from across the Multiverse. And Kal-El, the Man of Steel himself, is next on the list. To stop this interdimensional terror, our world's greatest hero must join forces with the Justice League incarnate - an impossible team of super-beings drawn from across the 52 Earths - to track down the kidnapper and free his Kryptonian counterparts. At the same time, trouble of a different sort is brewing right in the Kent family's backyard - and both father and son must rise to meet the challenge!
