Lin Jianghan, a genius from the northern Qing Dynasty, was abandoned and raised in Heishui Village due to his parents' divorce. This mountain village with dangerous waterways and frequent drownings hides taboos more terrifying than the undercurrent. Suffering from affective disorder, he is haunted by evil spirits and enters the mysterious world of corpse collectors - the "death fall" determined by the compass, the modern wisdom in paper-tying techniques, the poignant sacrifice of a living coffin that attracts hundreds of ghosts... When "The Water Monkey Marries" A corpse floating in human skin suddenly appears, and when the ancient corpse backfires and triggers a thousand-year curse, Lin Jianghan joins hands with Liu Sangeng, an old corpse collector who bears the fate of his family, and Bai Xiaoli, an archeology girl who feeds ghosts with his body. In a bizarre murder case in the style of a unit drama, they unravel the bloody truth shrouded in the fog of folklore. Every floating corpse is a mystery, every exorcism is a game of life and death, and the Cave of Rebirth deep in Blackwater Village is waiting for them to open the taboo door with the destined answer.
