In the middle of the night, the police department investigates a fatal bombing at a Wayne Enterprises construction site. Signs point towards this being the work of militant OGs (Original Gothamites), disgruntled with the many slights and difficulties they have suffered even since Gotham returned to being part of the United States. However, OG spokesman Roberto Alonzo, a former associate of the Black Mask, points out that this is very unlikely, as Bruce Wayne is one of the few employers to have treated the OGs with the respect they deserve and given them the help they need. James Gordon comes under pressure from Mayor Dickerson, who wants an arrest quickly, both to appease the construction firms working in the city and to give him a soundbite at a press conference - in fact, he wants Alonzo arrested immediately, but Gordon will not authorize any such action without concrete proof.
Meanwhile, Batman investigates Francis Piper, a known criminal who has been seen at some of Alonzo's rallies. Even as Alonzo is arrested due to his name being used to rent the car which was turned into a carbomb, Batman discovers that Piper had posed as Alonzo, stealing his wallet, in order to cast blame on the OG leader. However, Piper claims that he does not know who hired him to do this. Alonzo is released, but he is attacked soon after leaving GCPD headquarters, and his body is strapped inside another vehicle which is blown up at another construction site, this time belonging to Coldwell and Ferris Construction.
Roberto Alonzo's body is found at the scene of the second construction site bombing and the Mayor sees this as proof that the OG spokesman was responsible. The police department and Batman, however, are not convinced and continue their investigations. Batman discovers that explosives were carefully planted throughout the site of the second bombing, meaning that a demolitions expert was involved, and James Gordon discovers that the site was seriously over-insured. They both reach the same conclusion by different methods - Vic Ferris of C and F Constructions, is responsible for the bombings, both to collect on insurance money and to turn opinion against the OGs, who he believes to be scum. With the help of Ferris' partner JJ Coldwell, they are able to arrest him. He even gets a punch in the face from Commissioner Gordon, who takes him to task for his attitude to the OGs - not for himself, since he was raised in Chicago, but on behalf of his late wife, Gotham born and bred and a casualty of the No Man's Land year.
