The zombies are engulfing the city, and the defense line of the old shelter is about to collapse. Former fire captain Chen Lie couldn't help but light the gasoline barrel. The fire engulfed dozens of living corpses and burned out the survivors' last escape route. He walked out of the fire amidst the ashes and smelling of burnt flesh. Everyone knelt down tremblingly and begged him to become their leader. Doctor Zhao Wanqing is bandaging burns while calmly calculating supplies, veteran Sun Guodong secretly investigates the hidden truth behind the fire, and high school student Lin Qiao's screams indicate that the next wave of corpses is coming. Chen Lie took the gun handed over by Zhao Wanqing, knowing that this fire was just the beginning of the doomsday order.
