Ten years ago, an unsolved murder took away the father of primary school teacher Shen Zhixu. At that time, trainee police officer Xu Yi once handed her a tissue, but he was unable to change the dusty ending of the case.
Ten years later, it was rainy and gloomy in Nanwu, a small southern town. When criminal police captain Xu Yi was faced with a new murder case, the cold knot at the scene that was exactly the same as the old case was like a key, suddenly opening Pandora's box that had been sealed for ten years. The note "Next, it's your turn" from the deceased's mouth pointed the finger at the core figure of Hongyuan Construction at that time - Shen Zhixu's father Shen Jie was among them.
The storm of ten years has finally stopped. Xu Yi pressed his bright red fingerprint on the closing report, ending this bloody cycle that spanned ten years. Looking at the ten-year snow falling outside the window, he walked towards the woman who had been run over by the wheel of fate and whose heart had turned to gray. His voice was hoarse but filled with ice-breaking determination: "The case is closed, can you let me... Accompany you out of this ten-year snow?"
Concept: The new case leads to the old case, and the male and female protagonists reunite.
