Twelve-score Years and Ten

By the year 3010, fallout from successive wars has made the planet's surface unlivable. Humanoids live underground like termites and a final conflict threatens all life.Those in the Western Alliance bunker have vastly increased their lifespan but reduced their population to 50 because they regard humans as intrinsically destructive.
The privileged 300+ years-old elders in this gerontocracy have been preserved at the physical age of eighty. They are maintained by robots and a eugenically streamed, short-lifespan humanoid underclass. To curb veniality further, they are obliged to live by three stringent edicts distilled from the behaviour of social insects—Conformity, Rigour and Utility.
Mark5 is a sub-class Sex Cadet streamed to service women elders and he'll do anything to survive as he navigates his way through the carnage and collapsing infrastructure of earth's final brutal civilization. This bizarre dramatization of the fag end of civilization is stylish, clever and unpredictable.
