It is 20 years after a devastating nuclear war between the Pan-American Confederacy and the Euracs, an alliance of European, African and Asian forces. Massive contamination from radiation has largely sterilised humanity; no new human beings have been born for 20 years. The Euracs have occupied Noo Yoik and are scouring it for survivors, on whom they conduct intensely painful and invasive medical tests in the hope of finding anyone capable of producing children.
Meanwhile, the defeated Pan-American Confederacy has regrouped in Alaska (or an amusingly poor model thereof), where their leaders have discovered through old census records the existence of a woman in New York who could viably become pregnant. (How records largely compiled before the downfall of civilisation that caused mass sterilisation can indicate this is, shall we say, one of several plot points which are glossed over due to not making a lick of sense. (It actually makes sense in the end, but it seems like Parsifal is caused an awful lot of problems by the fact that the Confederacy leaders don’t bother giving full details to him.)
Parsifal (Michael Sopkiw), a badass road warrior who has a troubled history with the Confederation, is recruited by them to go on a mission into Eurac-occupied New York to retrieve the woman in question, so her eggs can be surgically harvested and used to make a viable new population on a colony mission to Alpha Centauri. Along the way he’ll have to tangle not only with various local ragamuffins and Eurac soldiers, but also the animalistic gang led by Big Ape (George Eastman), who dress in old-timey costumes and for some reason include a bunch of Neanderthal-types and full-blown Planet of the Apes-esque talking apes.
