Living (played by Zheng Jiaying) is a zombie hunter with an immortal body. He hides his true identity and hopes to capture the zombie Lingfeng (played by Chen Shancong) who has a hundred years of hatred with himself one day. He Nian (played by Huang Younan), He Yue (played by Chen Jiabao) and Jian Tingsi (played by Lu Yong) are living apprentices. Living teaches them the ability to hunt zombies. A line of people is the left and right arm of living who trusts very much. By chance, living learned that there was a female forensic doctor Mengnan (played by Xie Anqi) with special functions. She could talk to the corpse for one minute. As expected by living, Mengnan is a zombie hiding among humans. Living wanted to kill Mengnan to fulfill his duties, but was bitterly blocked by Mengnan's grandmother Huang Zihong (played by Luo Lan). In addition, Mengnan has always suppressed her nature and never hurt humans, so living gave her a break. One day, Menglan accidentally reveals her true identity in front of her sister Mengyao (played by Grace Chan), which frightens Mengyao so much that she suffers a mental breakdown. Menglan stays alive by Mengyao's side and takes good care of her.
