Russ and Anne Mathews live in a rural suburb in Tennessee. Regular people, with regular jobs, living a normal life - except for one thing. They are what many people call "preppers".

They have stocked up on supplies to survive any kind of event they can think of that may occur to disrupt life as they know it. When that event comes, they start preparing for the new way of life they will face. Along with their teenage son, and their next door neighbors and best friends, they plan their exit from a neighborhood too close to the city to a farm in the country. They just have to get there.

Their faith in their own capabilities and in humankind will be challenged, as they fight to protect and keep their supplies and, quite possibly, their lives.
