When corpses in barrels with mysterious tattoos appear one after another in the city, police captain Zhao Jichuan is involved in a conspiracy that goes far beyond ordinary murder cases. The forensic doctor Yue Qingran who assisted in solving the case was extremely talented, almost abnormally calm, and his dedication to the case far exceeded the requirements of his duties. As the investigation deepens, clues point to a core member of an overseas organization code-named "Doctor" - and this person is actually deeply related to Zhao Jichuan's past. They approached the truth amidst the rotting corpses and the smell of formalin, but no one realized that the real hunter had been standing among them.
