Traces of Cold Cases

Under the neon lights of Nanzhou City, there are always shadows hiding unknown secrets. Lu Chen, a 28-year-old detective from the crime team, is used to looking for the truth in the dust at murder scenes - a fingerprint in a strange position, a fiber that is inconsistent with the environment, and even an abnormal light spot in the deceased's pupil that has not dissipated. The team he formed with Su Rui from the technical department, veteran detective Zhao Peng, and newcomer Lin Wei handled every case like a tangled web: a seemingly accidental fall from a building contained half an old photo held tightly by the deceased; a suicide in a secret room had DNA that did not belong to him under his fingernails; behind the serial theft case, it actually shared the same symbol with an unsolved case ten years ago. Each case leads to colder clues. When the scattered spider threads were connected one by one, they discovered that all the deceased had touched the same taboo. But Lu Chen didn't know that he was already part of this giant network.
