On the banks of the Qinhuai River, several strange murders occurred one after another. The deceased were all young women. Their eyes were gouged out and filled with cinnabar. There were still bloody shadow puppet fragments next to the bodies. During the investigation, the police gradually uncovered a secret related to the fire at the Hongxiufang Theater twenty years ago. Back then, in order to complete a shadow puppet show called "Blood Shadow", Su Wanyue, the daughter of the theater leader, did not hesitate to make shadow puppets out of human skin, and tried to open the door to eternal life by sacrificing five pure yin girls. Detective Chu Chen and Huadan Liu Ruyan of Hongxiufang (actually a descendant of Su Wanyue) conducted an in-depth investigation together, and finally discovered that Liu Ruyan was the fifth sacrifice. On the bank of Jinghu Lake, the police officers confronted Su Wanyue's soul, and finally stopped this twenty-year sacrifice conspiracy with the help of the seal left by Captain Su.
