[Suspense criminal investigation + dusty old case + multiple reversals + human redemption]
In 2017, it was the rainy season in Yunfeng County.
Provincial criminal police officer Shen Du sent down to the grassroots and took over a "death case" that no one dared to touch.
Seven years ago, a woven bag filled with corpses floated in the Yudai River.
The murderer was extremely ruthless and left no trace at the scene. He could not even find out who the victim was.
Seven years have passed, the files have turned yellow, and all clues have been lost. Everyone thinks that the truth will rot in the mud forever.
It wasn't until Shen Du reopened the blood-stained file that he was shocked to realize that he was stepping into a deeper situation step by step.
"Some cases solve crimes, and some cases solve lives."
As the investigation deepens, a pair of siblings with a complicated relationship emerges.
What kind of unknown past is hidden between them?
Who is guarding that broken "home" in the most cruel way?
