Qiu, the captain of Hangzhou City Criminal Investigation Detachment, is an orphan of a police officer who grew up in an orphanage. He is not afraid of anything but being owed favors. Xu Jin, a criminal policeman with a background as a forensic doctor, was short-tongued and venomous, seeking advantages and avoiding disadvantages was written in his genes. However, in his sophomore year of high school, he was exchanged for his life by a man. From then on, he bet all his courage on that person for the rest of his life.
A case of serial dismemberment of thirteen people, a six-pointed star-shaped layout of corpses, and a provocative phone call made directly to the city bureau's landline put the city's police force into a passive position. At the same time, an office worker named Xie Hen was plotting a revenge in the darkness of the city using methods unknown to them, weaving a web of hatred - he didn't know that his father, who died early and was said to have "inaction", and Qiu's parents who died in the same mission were actually on the same side of the same thing.
Qiu and Xu Jin chased the murderer side by side, and slowly became entangled in each other's lives from two parallel lines. One thought it was repaying a favor, and the other thought it was just a partner. Until that day, Qiu discovered that Xu Jin's mobile phone password was the day she joined the company - which happened to be the same day as Qiu's birthday.
And the secret hidden behind this little thing was born many years earlier than the corpse dismemberment case itself.
Five murder cases, the relationship between the two of them will be in this long battle - from mutual silence to life and death.
This time, no one will hide anything from anyone.
Intention: When everyone and the system fail you, remember to choose to be the person who will not be buried.
