In the Year 2889

Nuclear war devastates much of the world, but old man John Ramsey (Neil Fletcher) manages to survive, and he holes up on his rural property with his daughter, Joanna (Charla Doherty). Because John always believed in the inevitability of nuclear apocalypse, he'd prepared the house with plenty of provisions. Other survivors of the disaster start to show up at the house demanding refuge. John reluctantly lets them in, but there is much tension. Then the mutants appear.
