The Old Case Is Serious

Twenty-eight years ago, in a nursery on the outskirts of Qingchuan, a woman, Su Mei, disappeared mysteriously. There was no body, no witnesses, and the task force argued endlessly. The two groups of suspects took turns to investigate, but were eventually released due to insufficient evidence. The case was sealed in the archives, becoming a backlog that no one wanted to touch. Retired detective Zhou Cheng has been trapped in this case for half his life. The city bureau formed a cold case investigation team, and he voluntarily returned to the team and restarted the investigation together with young police officer Jiang Yu. A bag of garden soil sealed for twenty-eight years became the only hope to break through the fog. As the investigation deepens, old cases that have been covered in dust for more than ten or even thirty years have surfaced one after another. Under the old files, there are forgotten victims, murderers who got away by chance, and omissions and regrets left by the investigation back then. Across a long period of time, delayed justice breaks through.
