Criminal police captain Jiang Yan was accused of killing a family of five. His DNA in the autopsy report became irrefutable evidence, causing an uproar in the city. Forensic doctor Lin Zhao issued the report himself, but burned the original data late at night. The only surviving witness girl drew a red old house, and Lao Scar, the corpse collector who was abandoned by the police force, actually recognized the layout of the painting. When Jiang Yan escapes from prison to track down the real culprit, Lin Zhao's secrets, Chen Rui's recording, Zhou Ting's machinations, and Lao Scar's old hatred all explode in the cracks in the autopsy report. The truth is far dirtier than killing.
