The "flying stone" at the Qingyun Mountain scenic spot suddenly fell and killed the beautiful woman He Luofei. When the police and everyone thought it was an accident, Song Wei realized that it was a murder and investigated.
Was it He Luofei's colleague Ye Changshu, or was it someone else who pushed down the "flying stone" and killed her? Doubts abound. Song Wei, Cheng Xi, and the police officers broke through the fog and finally captured the murderer.
