During a meeting with his senior officer, Inspector Yip (Deanie Yip), Star jokingly suggests he wish to be reassigned to the traffic unit. Star immediately finds himself demoted to Constable engaging in traffic duty on the streets of Hong Kong. After being made the scapegoat for a failed high school terrorist investigation, Star hastily resigns from the police. He decides to enroll at the high school to launch his own private investigation. But Star realises the investigation won't be easy when he discovers that the bumbling, incompetent CID detective Tat (Ng Man Tat) is also undercover at the high school.
