This was a weekly year-long event, similar to “52” and “Countdown” but unlike the latter, it was an entirely self-contained story. Unlike either of its predecessors, however, it focused on the major super-heroes of the DC Universe, Superman, Batman, and Wonder Woman, instead of the lesser developed characters.
Each issue of Trinity had two stories; the main one, focusing on the Trinity themselves, and the backup, focusing on other characters involved in the overall storyline.
With Superman unconscious, Wonder Woman attacks the alien Konvikt, trying to take him down. Superman comes to and takes hold of Konvikt and his partner Graak, flying them high into the air, giving the other heroes a chance care of the citizenry while he attempts to speak to the marauding alien which does not have the ability to fly. Graak, however, proves that they are not as helpless as Superman believed they’d be, hitting him with an energy bolt and sending the aliens falling to the ground while Firestorm, Vixen, and John Stewart arrive to back up Superman.
On the ground, Black Canary directs the rest of the Justice League in securing the town, while, separately, Batman scares a small family into leaving their unsafe hiding place. Elsewhere, Wonder Woman starts save people from a building, but since she can’t do it fast enough has to convince them to save themselves by walking across a beam. The building begins to collapse as the last people are getting out, but Superman flies in and holds it up long enough to allow their escape.
In Castle Branek, Morgaine le Fey is watching the happenings in Massachusetts, with Enigma asking her if she’s enjoying herself. She tells him that her “agents are in place”, then comments on the symbolic nature of the Trinity; saying Superman is a Savior, Wonder Woman inspires others to achieve, and Batman scares the hell out of people. Enigma tells her to keep watching, confident she’ll find more to Batman than that, to which she mocks his “adoration” of Batman again. When she notes that he’s just a man in a costume, Enigma says there’s more kinds of strength than “raw power” and asks where she thinks Batman is and what he’s up to while the others are battling Konvikt and getting nowhere.
In town, Konvikt is making short work of League members until both Superman and Wonder Woman fly directly into him. He throws them off of him, the yellow hair on his shoulders, arms, and head turning to armor as he follows them to the nearby hills to continue the fight. While Wonder Woman recovers, and warns Superman about the armor, an arm reaches out from the bushes behind her and places a red sphere against her shoulder, burning a symbol into it. While she’s distracted Konvikt leaps at her, only to have Superman yank him back by the armor on his head. Wonder Woman tells Superman she’s can continue the fight, and he tells her that’s good because they need to give Batman more time.
Watching, Le Fey wonders aloud what they’re buying time for since he’s not even there, to which Enigma says that if it was him, he’d be following the aliens backtrail, seeking information.
Outside of Thayer’s Notch, Batman locates and enters Konvikt’s ship. Radioing back to Superman, he reports it to be an multi-species escape pod with suspended animation capabilities. As he readies to look around more, Graak readies an energy bolt from behind him.
