The show is set in the Justice League’s prime after the death of Superman. The League is extremely broken apart, everyone dealing with loss their own way. Batman has alienated himself from everyone, Wonder Woman has returned to Themyscira, Green Lantern (John Stewart) has been assigned to another squadron, Hawkman and Hawkwoman are to attend to royal duties in their home planet, and Martian Manhunter is on a mission to restore peace on his planet, among other missing leaguers. The only ones remaining are Flash (Wally West), Plastic Man, Doctor Fate, The Question, Steel, Captain Atom, Hawk and Dove, Booster Gold and Blue Beetle (Ted Kord). Now thinned down a tad, the league has accepted a few new members for the time being, who are Nightwing, Batgirl, Supergirl and Red Arrow (Roy Harper). Now with this new squad, they must continue to serve the earth a few heroes short. And larger forces may be looming as the squad progresses, only time will tell.
