When the person who retrieves the corpse becomes a sacrifice, who will retrieve the truth?
Ling Xiao, a man who fished corpses from the Yellow River, never thought that his master Mo Yuan, who was revered like a god, was the real murderer of his father.
Reporter Su Wan lost his previous memory in an incident, but during a follow-up interview, he dreamed back to three years ago when his father drowned mysteriously for violating the "three no fishing" taboo. Ling Xiao (Su Wan) inherited the mantle of a corpse collector, but found a jade pendant engraved with the "yin marriage" rune in front of his father's grave - exactly the same as the totem on Mo Yuan's cuff. As the investigation deepened, he was shocked to discover that the frequent "water monkey dragging people" incidents in the village were actually Mo Yuan's experiment of using human beings as sacrifices to the "Black Water Evil"; and the legend of the so-called "Gate of Underworld" was actually Mo Yuan's evil ritual in pursuit of eternal life.
In order to take revenge, Ling Xiao repairs the soul-suppressing umbrella left by his father, and joins forces with Qingyao, a descendant of the tomb keeper, and Mingxuan, a criminal investigation expert, to start a life-and-death game with Mo Yuan. When the truth was revealed layer by layer: the thousand-year oath of the tombkeeper family, Mo Yuan's path to redemption after depravity, the cruel truth that his father's body was made into a formation eye... Ling Xiao finally understood that he had become a key piece of this conspiracy.

When Mo Yuan stood under the Gate of the Underworld and said these words, the Yellow River shovel in Ling Xiao's hand began to tremble for the first time...
