A rag-tag band of survivors of a nuclear holocaust head for Albany, New York, the only city in America spared in the apocalypse.  Tanner, Denton and Keegan are co-workers at an underground military facility.  They find themselves an all-terrain vehicle and set out for the (now) wilds of up-state New York.  Along the way they pick up a number of survivors, including a surly and incorrigible teenager.  On the way to their destination, they find themselves fighting not just mutant insects and the savage landscape, but themselves as they try to forge bonds to survive.
