In Linzhou City in the 26th year of the Republic of China, a continuous autumn rain unveiled the strange veil of Jingshui River. Forensic doctor Bo Jingchuan and detective Lu Xixiao were swept into the whirlpool by a bizarre floating corpse - the deceased Shen Qinghe had a lifelike face, with a waxy luster on his skin, a strange smile at the corner of his mouth, bluish scales hidden under his tongue, and a silver bracelet on his wrist that looked out of place.
The giant crawl marks on the river bank, the hair sacrifice at Jingxin Temple, the mysterious ancient city revealed at the bottom of the river... The clues are like a spider web. When the second and third corpses surfaced one after another, all bearing the same snake head mark and scales, the legend of "White Snake Queen demanding her life" spread wildly in the city.
Bao Jingchuan, who does not believe in ghosts and gods, discovers a scientifically unexplainable cause of death from suffocation during the autopsy. Lu Xixiao, who is determined to pursue the murderer, encounters the phantom of the woman in white during the pursuit. As the secrets of the sunken city and the millennium curse surface, the two are forced to face supernatural forces: is it the revenge of the dead souls at the bottom of the river, or the continuation of cult rituals?
When the seal of the White City is loosened and the full-moon rainy night approaches, they must decipher the mystery of the silver bracelet and scales before the death of the fourth victim, face the white-clothed "River God" who walked out of the legend, and uncover the dark truth about the Jingshui River that has flowed for thousands of years.
