One day, policeman Liu Yilu (played by Tony Leung) suddenly received a call on the road, telling him to dissuade "that" girl from committing suicide, because the girl's life and death will become a turning point in his life. Liu Yilu felt very puzzled by the call, and at this moment, two gangsters Gigi (played by Li Qihong) and Da Fei (played by Liu Yida) were fighting in the street, and Liu Yilu was accidentally hit by Da Fei's bullet in the throat. After being sent to the hospital for rescue, Liu Yilu's soul left his body and met a naked girl. After a conversation, Liu Yilu suddenly returned to the world, but the girl just now was lying beside him and died. Liu recalled the strange call before, and suddenly felt that this might be God's revelation, so he decided to carefully investigate the cause of the girl's death. It turned out that the girl was raped by the rich man Cao and then committed suicide by cutting her wrists, and the important witnesses Gigi and Da Fei also wanted to be killed by the rich man and began their escape. In order to follow the two, Liu Yilu actually returned to the Three Kingdoms era?
