1000 Years After Our
World Died – A Man and a Woman With the Future of Humanity in Their
Hands – The distant future – New York is a jungle in more ways than one. Exotic flora and fauna thrive – savage tribes of cannibalistic
sub-humans fight for dominance. It's a place of little hope! The last
vestiges of humanity set out across America's devastated landscape in
search of their dream. Led by hope that dies and is reborn again at
every turn - enticed onward by a mysterious and vast black chasm 500
miles deep – does the future threaten extinction for mankind? – or offer one last chance of redemption?
