Set on the coast of South Carolina, an unknown infection has caused people to die and come back to life as reanimated corpses, attacking any living person. This is the story of the survival of one man who was the benefactor of a shelter that helped him to live through the onslaught of the infected dead.

Rick, an aging Vietnam veteran, alcoholic, and prepper, convinces Zach Gunderson that the apocalypse is on the horizon. The two of them take refuge at a remote farm. As the zombie plague rages, they face a terrifying fight for survival. They soon learn, however, that the walking dead are not the only monsters.

Three years after an incurable virus spread and turned a majority of the population into mindless and cannibalistic creatures, the world is a barren place. Society is broken, and most who remain have banded together in small camps and communities. Jon South is not like most other survivors. After losing his wife and son nearly two years into the pandemic, Jon now wanders the country roads and woods of rural Tennessee, a vigilante taking his revenge out on the undead monsters that took his family from him.

It all starts with a single dead person coming back to life. Within three days, the undead have taken over most of town. Despite heroic efforts and swift initiatives from the government, disaster keeps spiraling. Soon, the infection reaches the nation's borders, threatening to become a worldwide pandemic.

Those who would seek a new world order have unleashed the most devastating virus onto mankind, and even they do not know the secrets hidden in their weapon. Follow along as Harry, a CDC scientist, races to figure out what exactly the virus is and how to stop it. It will be up to him and a group of marines led by Major Sanders to stop the zombie fallout before it ravages an unsuspecting world.
