Funeral parlor undertaker Gu Chuan has the special ability to see the last memories of the deceased. He has been used to seeing life and death for three years, but because of a female body found at the bottom of the river, he was involved in a fateful entanglement that spanned thirty years. There was a marriage letter hidden in the female corpse's mouth, and it was signed with Gu Chuan's birth date. The bloody words "I have been waiting for you for thirty years" on the back completely opened up the mystery of his life experience.
Under the guidance of his master, Gu Chuan opened the dust-covered "Entombment Record of the Netherworld" and learned that this was a life-threatening sign for a water ghost to get married, and that his fate had already been tied to the tragedy in Wanfu Town thirty years ago. At that time, the bridge construction in Wanfu Town was robbed. The Feng Shui master said "three thousand people were sacrificed to build the bridge", which turned the town into a hell on earth, and three thousand innocent souls sank to the bottom of the river. Only then did Gu Chuan realize that he was not an orphan, but a child who had been deliberately saved in that tragedy. The female body was actually his sister Gu Xiaoxi, who had been waiting for thirty years.
Three thousand innocent souls took advantage of his sister's body to ask for their relatives, and Gu Chuan was given seven days to die. Only by volunteering to stay at the bottom of the river for his sister could he solve this disaster. In seven days, Gu Chuan uncovered the truth step by step, saw clearly the sacrifice of his master, the obsession of the mysterious Taoist Zhao, and also understood the loneliness and despair of his sister who had been trapped underwater for thirty years. In the end, he chose to exchange his own body for three thousand innocent souls and jumped into the river. However, he met the young undertaker Song Yang at the bottom of the river and sacrificed his life for him.
After returning to Yang, Gu Chuan was burdened with the three commandments of "Entombment in the Netherworld", but met Song Yang's younger brother Song Yin by chance in a strange town. A request to "take care of my brother" made him break the commandments and go to Song Yin's burial pavilion, and the fate of the painter Yin Chai has just begun.
