After the events of the first season of Peacemaker and the epic conclusion of Justice League 3, Christopher Smith reunites with John Economos, Emilia Harcourt and Leota Adebayo, alongside a new character named Mark Shaw aka Manhunter, they embark into a new dangerous mission about stopping a zealot leader named Libra who has taken over the United Nations Goverment to protect criminals, sociopaths and supremacists from getting punished, all in the name of moral balance; meanwhile, US Goverment sponsored superheroes Captain Atom and Nightshade decide to target Peacemaker (who have known him for years) to stop him from murdering people in his way.
