In the murder case seven years ago, the testimony disappeared mysteriously, and the real murderer was at large. Wen Jinyan, the coldest blade in the forensic world, returned to the crime scene overnight just to regain the erased testimony. Qi Xiaoye, who was once his partner, is now the number one suspect wanted by the police. When the still-scarred corpse opens its eyes on a rainy night, and when the voice recorder transmits his own confession of murder, the two meet in a narrow gap in time - he wants the truth, and he wants to live. Who controls time? Who is forging testimony? At the scene where the blood was still wet, only the two of them remembered what happened that night.
