Thirteen years ago, a massacre occurred in City A. The police at the time said that no one survived, but was that really the case...
Su Yu (Shou) is a 26-year-old rumored genius in the police station. He is what they call a "cold beauty, a cold mountain for thousands of years." The veteran detectives secretly lamented: "Consultant Su's brain is better than the police station's database." He claimed that he had a top criminal degree, but he took the initiative to enter the police station. No one knew why this beauty took the initiative to enter the police station to become a consultant. No one knows how many unspoken secrets this man with exquisite fingertips hides: Why does he know the details of the crime scene so well? Why can you always predict the murderer's next move in advance?
Jiang Hai (attack) 30-year-old "little gangster" in the police station. As the most unruly "thorn" in the police station, Jiang Hai handles cases with ruthlessness and intuition. Some people say that his intuition is better than that of a police dog. In the new cases that follow one after another, he smells the seemingly invisible connection between Su Yu and the old cases from thirteen years ago.
Purpose: Two-way redemption and persistence of justice in darkness
