A team made up of heroes from the present and legends from the past, the JSA finds themselves fighting their history and their future, as they face off against the mad Obsidian, son of Alan Scott, the original Green Lantern and member of the Justice Society. and just as Starman, Hourman, Star Spangled Kid, Black Canary, Atom Smasher and Sand begin to recover from this emotional and physical battle, they find themselves pitted against their old foes, the Injustice Society, and the time-warlord Extant, the man responsible for the death of several members of the original Justice Society.
