After the war, the United States had kicked Hugo Hammer to the curb, and he was intent on staying there. He had suffered enough to help defeat the Nazis, and all he wanted to do was to waste away on the streets, one drink at a time. He wanted to be useless, a drag on society, so that no one would ever ask him to be a hero again.

But the Nazis were back, digging their way back to the surface and intent on conquering humanity. The world was still beaten and bloodied from the war, still trying to recover. Desperate, the powers that be turned to a man they knew had nothing to lose, nothing to hold him back, and who no one would miss if he didn't make it back. They turned to Hugo Hammer, Nazi Hunter. The world turned to him to kill Josef Mengele.
