Seventy-two hours after the zombie virus broke out, Chen Zheng secured a foothold in a warehouse on the outskirts of the city with the supplies he had stockpiled. When Lin Xiao, a mechanic, arrived with the badly injured Dr. Zhou, he realized he wouldn’t get far on his own. Grain merchant Zhao Desheng offered supplies but demanded exorbitant commissions. A boy named Xiao Qi brought up a blurry map from the sewers, while Scar, in the industrial district, was broadcasting fake safe zones over the radio. Chen Zheng must unite this group of survivors, each with their own agenda, and find the source of the virus before the zombie horde surrounds the city, because Lin Xiao has discovered that the zombies seem to know how to coordinate their attacks.
