When the apocalypse arrives, Lin Yu wakes to find the city overrun by zombies and heads out to search for supplies. He rescues a puppy named Jifeng, who then transforms into a dog girl named Linger. Along the way, they encounter a zombie horde. While taking shelter in an abandoned factory, they discover experimental equipment connected to the apocalypse. A mysterious radio signal guides them on their search, but zombies surround them and Linger is injured. They eventually find the source of the signal and learn that the zombies are connected to an evil organization. Later, they discover an abandoned military base containing advanced weapons and energy crystals. Lin Yu suspects the crystals are the key to turning things around, but armed men have their eyes on the base, and danger is closing in.
