On a night of heavy rain, there was no one on the road. Under the flickering street lights, a man in a black fur coat held up a black umbrella stained with blood... "Beep, beep, beep"... "The police have blocked Building A"... "Quick, quick, pull up the cordon."
"The age of the deceased was visually estimated to be 21, the time of death was more than 72 hours, and there was a view of a corrupt giant..."
There are many vicious murder cases with the same techniques in Linhai City. Is the murderer the same person? What unknown secrets are hidden behind the mysterious Nuo opera masks...
There were many bizarre murders one after another, so the evidence was like footprints washed away by the rain, meaningless - until the forensic doctor Lu Yuan discovered a Nuo opera mask under the soil where the body was hidden... The two were forced to cooperate, one was introverted and silent, the other was extroverted and talkative. The mutual dislike at the first cooperation turned into a tacit trust later, uh, and of course intimacy.
All of them cast a mysterious color on Linhai City in the rainy season...
Concept: When the truth is woven into an illusion by desire, the two people are entangled like twins. In the abyss of tracking down the serial murders, they are each other's only salvation, and they are also accomplices who will eventually step into the same burial ground.
