互動殺人事件

Pop star Anna has been kidnapped. Kidnapper Jash uploads the video clip of Anna being tortured onto the internet, which instantly becomes the talk of Hong Kong. A week later, Jash contacts the police, asking not for a ransom but for retired police inspector Mo to be his police contact. Inspector Mo eventually discovers through a tabloid magazine that a self-proclaimed psychic named Shana had phoned a radio program on the day of the kidnapping to warn of the incident.
