Shen Xu is the youngest undertaker at the funeral parlor in Jiangzhou City. While sorting out the remains of the deceased, he unexpectedly gained the ability to see the last image of the deceased. The drowning that was treated as an accident and the death that was hastily characterized were all details that needed to be verified in his eyes. Relying on forensic science knowledge, professional experience and a limited number of replays, he started from a mutilated nurse card to help the criminal police restore the truth and let every misunderstood person say goodbye with dignity. Someone once asked: "What do you know as an embalmer?" Until the case was reopened again and again, everyone finally understood that he was often the last person to see the truth.
