The New York SWAT team visits some of the city sewers in order to clean them from the tramps that live there. But that's also the Abomination's home, who reacts madly against those guests. Hulk finds out and travels to the big city to help the police. The two giants collide while a police officer fires at the harmless tramps killing most of them. The Abomination kills the shooter and directs all his anger to Hulk.
