In a light travel adventure, an ordinary guy goes driving around the country in his pickup truck--but with a nuclear bomb in the back of his pickup. Down at the local restaurant, Joe overhears an extraordinary conversation, a plot against America. He soon finds himself in possession of a "mystery object"--is it a nuclear weapon or a "dirty bomb" full of deadly virus? With the device in the back of his pickup truck, he embarks on a quest over five Southern states, trying to find someone to tell him what to do with it. And the interesting people he meets along the way.
