When the USS McClusky (FFG-41) was overrun by the dead, Machinist Mate First Class Jackson Creed, and Marine Sergeant Joel "Cruze" Kelly, were forced to abandon the ship, and take their chances in San Diego. Now they are stuck in a city that has been completely overrun with zombies and as the days go by they must range farther and farther away from 'fortress' in their search for supplies. Relying on military training, guts, and pure force of will, the two of them will face a nightmare world that is intent on killing them one bite at a time.
