In the first episode of a two-part story, John Stewart, aka The Green Lantern, must come to the rescue of his fellow "Lanterns," several of whom have pitted their lives against the alien minions of the evil Despero. John is alerted to this peril by another "Lantern" named Kilowog, who has escaped the villain's clutches and made his way to the headquarters of the Justice League. Complicating matters is the presence of Stewart's mentor and former sweetheart Kama Tui, who has apparently sold out to Despero.
