America's post-holocaust nightmare continues as Ryan Cawdor returns to the monstrous urban slum that was once New York City...and discovers a piece of the future...

 

As the roaming band of survivors seek desperately to escape the eerie wastes and mutated life-forms of their nuclear hell, they emerge from a gateway back into the ruins of Manhattan—the concrete battlefield where Ryan had avenged the death of his father and older brother.

 

The city is a flooded hell zone ruled by street gangs and hordes of reptilian mutants who inhabit the sewers. Under this urban ruin lives the self-styled King of the Underground, presiding over his subterranean fortress filled with pre-nuke memorabilia. And here, in this once great metropolis, lives a ten-year-old boy. He is Ryan Cawdor's son...

 

The children shall inherit the Earth.
