Near what was once the Pacific Northwest, Ryan Cawdor and his roving band of post-holocaust survivors discover a beautiful valley untouched by the nuclear blast that changed the earth forever. Resisting the temptation to settle in the idyllic land, the group is captured and forced deep beneath an extinct volcano to an isolated community of in-bred scientists who are blindly laboring to find better ways of genocide, unaware that the world they are striving to slaughter has already died.
