"Evidence on the Spot" tells the story of a crime that spans twenty years.
The story begins in 1993 when a boy fell from a tall building.
Twenty years later, another bizarre murder occurred in a high-end apartment in the center of Jiangcheng City. Former female detective Chen Xiaomin discovered the scene of the crime with her unusual sense of smell, and the smell of the scene was exactly the same as an old case she handled twenty years ago. However, the female suspect Miao Suyun, who had already surrendered to the law, appeared at the scene of the new crime again.
The murder of the art academy professor back then, the murder in today's wealthy business circle, the black transactions hidden behind the welfare home... All the clues point to the boy she calls "Little Tree". And Miao Suyun, this woman who has been silent all her life, what is she protecting in her own way?
This is a story about how sin is passed from generation to generation, and also a story about how ordinary people can redeem each other in desperate situations. When the dust of the past is stirred up again, everyone must face the consequences of their choices.
