A sudden outbreak of disease known as "The Haze" causes infected animals and humans to turn rogue. Man turns on man and humans slowly turn into brainless, thoughtless cannibales called zombies. They plunder towns and cities within days and weeks, leaving nothing but rubble and bodies. These zombies however, are different. They're smarter, faster, stronger. All communications are down. In Arizona, the town of Posey has lost most of its population. However, 8 teens band together and work to survive and get to the bottom of the outbreak.
