Following a deadly outbreak of influenza which decimates the population of the planet, the government issues orders that all remaining citizens are to report to designated Authorized Population Zones so that resources may be fairly distributed. Journalist Maggie Langton, determined not to let her son, Mark, grow up in the dangerous environment of the APZ, decides to run for the empty ranch land of northwestern Arizona. When she runs into O'Reilly, a fugitive ex-Enforcer, she grudgingly admits she needs help developing those skills needed to live on a small ranch camp. What she doesn't expect, however, is that with knowledge of how to live rough, O'Reilly also possesses a darker knowledge: knowledge much more dangerous, and knowledge which the government will do anything to suppress. Maggie and O'Reilly find themselves in a fight to keep their newly formed family safe and secure, and out from under the rule of the controlling new government. At the same time they discover a conspiracy much deeper than anyone had believed possible.
