In the first episode of a two-part story, several Justice League members are whisked off to an alternate reality, reappearing in Seaboard City, a town that seems permanently locked in the 1950s. Here the Leaguers meet their counterparts, the Justice Guild of America -- all of whom resemble the "Golden Age" versions of DC Comics' familiar superheroes. The League and the Guild team up to thwart the doppelgangers of the "real world's" villainous Injustice Gang, here known as the Injustice Guild. Throughout the action, J'onn J'onnz (The Martian Manhunter) continues receiving psychic messages indicating that what appears to be happening may not be happening at all!
