《No. 7 pavilions》 introduce
In the eyes of Fang Zheng (Xu Zhian), the senior inspector of the serious case team who has repeatedly solved strange cases, the colleagues of other departments who have been invited to the victory party are mostly mediocre. Many cases can be solved by himself and his brother Aze (Lei Yuyang) and others, so his words and deeds are somewhat arbitrary and arrogant. In a bandit arrest operation, he could not wait for the Flying Tigers to issue their own orders. Two colleagues were killed in the street. He was also shot unconscious and lay in hospital for two years. After waking up, his mother has passed away and his girlfriend has become another wife. The world around him has changed a lot, but Fang Zheng also accidentally reaped the love of the female nurse Oscar (Li Lizhen) who had been taking care of him when he was unconscious. The recovery training lasted for a period of time, and Founder was almost the same in all aspects as before the coma, with more ability to see ghosts. This skill made him panic at first, but the words of Ah Jie (Zhang Daming), who was a psychologist before his death, made him feel relieved. After returning to the police force, Fang Zheng volunteered to take over a case of rape and murder of a serial female nurse that has been unsolvable for two years. Within two years, six female nurses have been raped and killed, and most of them are dead. The reason why the case can be established is that one of them rushed to the police station to report the case to Azer. Fang Zheng was calm and determined that the murderer was a man with high intelligence quotient and was very familiar with the police's methods of solving the case. At the beginning of the case, Fang Zheng was told by Ah Jie that Oscar's life magnetic field was getting weaker and weaker, and she might be the next target of the murderer.
屢破奇案的重案組高級督察方正（許志安）眼裡，慶功會上紛紛邀功的其他部門同事多是平庸之輩，多起案件能偵破全靠自己和手下兄弟阿澤（雷宇揚）等人拼命，囙此他的言行多少有些獨斷高傲。 某次緝匪行動中，他等不及飛虎隊自行下達命令，兩名同事斃命街頭，他自己也中槍昏迷，在醫院一躺兩年。 醒來母親已過世、女友已成他人妻，身邊世界已大不同，但方正也意外收穫在他昏迷時一直悉心將他照料的女護士Oscar（李麗珍）的芳心。 恢復訓練持續一段時間，方正各方面已與昏迷前幾乎無差，更多出可見到鬼的本領。 此本領起初令他恐慌，不過生前是心理醫生的阿傑（張達明）一席話讓他放下心來。 回到警隊後方正主動請命，捕手一宗兩年來無法破解的連環女護士奸殺案。 兩年內，已有六名女護士被奸殺，且多數死不見屍，該案能立是因其中之一自己趕到警察局向阿澤報案。 方正冷靜頭腦，認定兇犯是一名智商極高的男性，且非常熟悉警方的破案手法。 案情漸有眉目之時，方正被阿傑告知Oscar的生命磁場越來越弱，她可能是兇犯的下一個目標。
