Shen Che is the leader of the serious crime team of the criminal investigation detachment. He is 30 years old, with a cold and decisive personality, and is almost paranoid when handling cases. Because of a miscarriage of justice while investigating a serial murder case three years ago, which led to the death of his partner, he has lived in guilt since then. He is used to paralyzing himself with work. In his life, there are only two points and one line: the office and the rental house.
Wen Shi is an expert in criminal psychology. He is 28 years old. He has just returned from abroad and joined the city bureau. He looks gentle and thin, and his words are soothing, but he can accurately analyze the psychology of criminals. She seems to be impeccable, but in fact she has an unknown secret - she is the sister of the victim of the serial murder case three years ago. She returned to China not only for professional reasons, but also to find out the "hidden story" of the case that year.
The two had to stay together because of the investigation, and at the same time they were caught in the struggle between "revenge" and "empathy"
