"City, Crime"
Three years ago, Zhou Wei, the youngest murder profiler in the police force, made a fatal mistake, causing his master to die tragically under the knife of the "Rainy Night Butcher". He took off his police uniform, wrapped up his guilt with a jokey ruffianism, and hid in the city from then on, never wanting to touch the scene of the crime again.
Three years later, the body of a woman who imitated the crime was discovered in a village in the city. Her death was exactly the same as that of the unsolved case back then. Jeremy Lin, the detective and chief detective, forcibly dragged him back to the police line. The new policewoman Yang Fang only thought of him as an idle gangster when she first met him. However, the moment he leaned over to look at the body, he saw that all the laughter had faded away and he was cold-blooded - the dead don't joke, so I won't joke.
He is a non-staff consultant to the police force, a ruffian who keeps talking, and a genius profiler who can identify the murderer in three minutes. The seemingly random imitation case leads to the real murderer who was still alive three years ago step by step. The other party uses the murder case as a challenge and his brother's life as a bargaining chip, forcing him to face the unfinished redemption.
From tit-for-tat to life-and-death sharing, Zhou Wei, Jeremy Lin, and Yang Fang formed the iron triangle of criminal investigation, peeling off cocoons in serial murder cases and digging deep into the fog of old cases to uncover the truth. When the ghosts in the police force surfaced, and when the truth about his master's sacrifice was revealed, Zhou Wei finally understood: some scenes must be ended by his own hands; some debts can only be repaid with justice.
He once fell into the abyss due to a mistake, but now he returns with the light, just to let every unfinished scene usher in the final truth.
