Florida Everglades, 2095 A.D. Phillip "Mack" MacKenzie has lost a lot. He is convinced the Russians are after the spaceship he designed, and his paranoia has driven him deep into the Everglades to live in isolation. Here he remains until NASA plans to sell his ship to Russia. After so much sacrifice in the name of science, he will not let the ship go, so he will take it to the one place where they can't chase him -- space.
