Qin Yu, a trainee forensic doctor, was involved in a car accident. When he woke up, he had a problem - he had "flashbacks" when touching the corpse and could see fragments of the deceased's memory of the last three minutes before his death. The picture is blurry, the sound is intermittent, the perspective is confusing, and sometimes there are even "double flashbacks" in which the memories of the deceased and the murderer are intertwined. The first time he used this ability, he solved a hit-and-run case with the sound of brakes and the reflection in the car window, and was spotted by Shen Kuo, the criminal investigation captain of the city bureau.
After joining the crime team, Qin Yu touched the victim in the "Rainy Night Throat Cutting Case". What he saw was not the murderer's face, but an old scar on the ring finger of the murderer's left hand - exactly the same as the one on Shen Kuo's hand. The bigger problem is that the victim's last thought before his death was: "Tell Xiaoyu to run."
Qin Yu didn't know this woman at all. And when he looked through the old files, he found that at the end of every unsolved case file in the past ten years, someone had written the same date in red pen - the day when his parents died in an "accidental fire" when he was three years old. The last thoughts of the deceased before their death were directed one after another to his long-dead parents and the man who had always stood by his side.
