In the summer of 2002, Mianzhuang Village was shrouded in continuous rain. After a rainy night, a murder was discovered in the wooden house by the lake - the deceased was the driver who had killed someone in a car accident, and the murderer turned out to be Zheng Yi, the son of the victim three years ago. He voluntarily surrendered, but remained silent on the details of the crime.
Criminal investigation captain Rosen led the team to investigate and found that the case was full of doubts
Zheng Yi calmly confessed, but refused to explain the motive and process.
Heavy rain washed away the scene, and blood stains and footprints were dissolved by the rain.
How did the tragedy of a car accident three years ago turn into today's killings?
What role does the strange man who suddenly appeared outside the police station delivering clothes on a rainy night play in the case?
Step by step, he peeled off the cocoon and uncovered the suspect's hidden hatred; but Rosen realized that behind this "revenge", there might be a colder truth...
Purpose: live a good life
