In the film's vision of 2019, Earth has been ravaged by a 1999 nuclear conflict between the Pan-American Confederacy and the Eurac Monarchy. Manhattan serves as a fortified headquarters for the victorious Eurac forces, who hunt irradiated survivors for genetic experimentation. The planet is a literal and biological dead end, characterized by a radioactive atmosphere and a total lack of new human births for over fifteen years.

Societal dynamics are defined by a desperate search for genetic viability. While the Eurac Monarchy employs fascistic control and vivisection to solve the sterility crisis, the remnants of the American Confederacy operate from secret bases in Alaska, planning a complete exodus to Alpha Centauri. This timeline diverges from reality through its depiction of Earth as an abandoned husk, where mutant tribes and 'Rat Eaters' populate the ruins of urban centers, and cyborgs are viewed with deep-seated biological prejudice.

The film’s central prediction of mass human infertility serves as a thematic precursor to later works like Children of Men, though its 2019 reality saw global population growth rather than collapse. Technological predictions include hibernation chambers and sonic weapons used for crowd control, which have minor parallels in modern long-term stasis research and non-lethal acoustic devices. Its geopolitical map of "super-states" reflects 1980s anxieties regarding hemispheric blocs rather than the fragmented, multipolar reality of the actual 2010s and 2020s.
