While trying to apprehend some fleeing criminals, Jing is shot in the head and two of his underlings are fatally wounded. After two years in a coma, Jing comes to and experiences some frightening visions. However, these are not nearly as disturbing to him as the revelation that fellow patient Kit (Cheung Tat-ming) is actually a ghost. He explains that Jing's lengthy sojourn between the realms of life and death have left him with heightened sensory abilities, hence the apparitions he now sees on occasion (people who died of natural causes look normal, while accident or murder victims retain their mangled form).Under the care of pretty nurse Oscar (Loletta Lee Lai-chun), Jing's health quickly returns and he is able to rejoin the force. Not long after Jing was shot, a serial killer started preying on nurses and has murdered seven to date, though only three bodies have been recovered. What is especially strange about the latter fact is that the victims themselves reported their own murders and two of the officers who were given this information have since died. The remaining policeman is Jing's longtime friend, Jap (Simon Lui Yu-yeung), who is understandably worried about his own safety. Jing takes over the serial killer investigation and Kit warns him that Oscar's life meter is shortening, indicating that she will likely be the next target. Using his newfound ability, Jing is able to speak to the spirit of the latest victim but, even with this supernatural assistance, the murderer remains elusive.
