Def Con 4

While the astronauts of the Nemesis Missile Station are in orbit, World War III erupts on Earth in a convulsive holocaust of nuclear fury. Months later, the spaceship crash-lands back on Earth, where the crew finds a wasteland ravaged by radiation and overrun by desperation, disease and cannibalism. When they’re captured by a group of sadistic survivalists, the astronauts must fight to save themselves and the world from total annihilation.
