The Gravedigger in the Line of Fire

The story took place in old Shanghai in the 1930s. A kidnapping case occurs in the jurisdiction. Detective Zhong Lang (played by Zhong Hanliang) determines from the words of the mentally retarded child A Ding that the perpetrator was a gravedigger who appeared two years ago. Due to the negligence of detective Ning Erkun (played by Zhao Yi) at the time, the tragic death of both Liao brothers was caused. In order to get more clues, Zhong Lang, Yang Ning and Erkun asked Mr. Liao to open his son's coffin for an autopsy, and sure enough, new evidence was obtained. At this moment, forensic doctor Yu Shengnan (played by Qi Fang) and detective Han Fei (played by Shi Xiaolong) were kidnapped by gravediggers. Through combing and analysis, Zhu Guoliang (played by Xu He), the adopted son of the owner of the slaughterhouse, came into Zhong Lang's sight. Because Zhu's father failed to borrow money from the Liao family and committed suicide, the paranoid Zhu Guoliang started to take revenge on the rich. Zhong and Ning worked together to rescue Yu Shengnan and Han Fei, but Ning Erkun and Zhu Guoliang both died in the gunfight. From then on, the gravedigger disappeared. Unexpectedly, at the wedding of the bride Liu Xiuzhu (played by Liu Zifei), strange things happened again...
