Three years ago, female detective Shen Zhiyi found a death list from an unknown female corpse. There were only two names on it - the deceased and her name. Three years later, the same list appeared again, this time with an additional name: forensic doctor Lu Yanzhou. When the third body was discovered, the names on the list had increased to six, all related to Shen Zhiyi. The murderer seemed to be hunting according to certain rules, and every deceased person had blocked Shen Zhiyi from fatal disaster. Shen Zhiyi must find the person who wrote her name in the dark before everyone on the list dies. The key clues provided by reporter Cheng Shuang point to an old case fifteen years ago, and all the answers are hidden in the files guarded by captain Zhao Yanqing.
