Start Solving Big Cases from the Police Station

On a rainy night, the Chengnan Police Station received a report that an elderly man had gone missing. Rookie policeman Lin Chuan thought it was just an ordinary police call, but he found a layer of bright yellow mud on the soles of the old man's shoes - it was not soil near the community, but old mud found only in Qingjing Old Street seven kilometers away. Hidden in the middle of the old man's clothes is a photo of a female student who disappeared ten years ago. That case was an old case that Lin Chuan's father failed to solve and therefore left the criminal police force. Starting from a small incident at the police station, every inconspicuous scene reveals a corner of the old case ten years ago. Lin Chuan does not have the aura of a detective, he will only focus on those irrational traces, and find the names hidden in files, medical records and death certificates one by one.
