It's the end of an age, and just in time for the end of everything else too. In suburban South Florida, Warnie Hargood is walking his mail route for the last time before retirement when his customers suddenly start trying to eat him. With nothing to lose, the 85 year old mailman decides retirement can wait. He has a calling, a duty that will go unfulfilled if it's not done by him. At the end of the world as we know it, there is still mail to be delivered, and Warnie swore long ago that nothing would stay him... ever.
