Follow the residents of the small town of Mawinhaken, Pennsylvania, as a sudden zombie outbreak turns an ordinary day into a fight for survival. When the dead begin rising and attacking the living, chaos quickly spreads through the streets, hospitals, and homes of the town. A group of strangers, including a former soldier, a mortuary assistant, local teenagers, and emergency workers, are forced together as they try to escape the growing horde and protect the people they care about. As the outbreak worsens, the survivors discover that fear and desperation can be just as dangerous as the undead surrounding them. Relationships are tested, hidden secrets come to light, and several characters are pushed into making brutal choices in order to stay alive.
