Professor and explorer Lin Xiaofeng strayed into a mysterious village called "Shayu Village" in order to find out the truth about his father's disappearance in Lop Nur.
Here, the villagers are very secretive about the "sand sacrificial ceremony", and the air is filled with weirdness and depression.
Lin Xiaofeng found a diary in the B&B where his father lived, which contained shocking words: "The red rope is a seal, there is something under the sand - they are feeding it."
Late at night, a strange camel bell rang, and a dark red rope was tied to his door.
In order to uncover the cause of his father's death and to escape, Lin Xiaofeng followed the guidance of the red rope and broke into the sand dune grotto behind the village.
There, he saw his father's relics and a creepy mural: a group of people tied "sacrificial offerings" with red ropes to the "Sand God" in the dunes.
What shocked him even more was that he learned from a mysterious old man that his father did not die accidentally that year, but was selected by the village to become a "sacrifice" to suppress the "Sand God".
And now, this village has chosen Lin Xiaofeng's partner, □□, as the next "sacrifice."
Facing the strange "sand whisperer" and the terror from the depths of the desert, Lin Xiaofeng must uncover the secret of the "sand whisperer" before dawn and escape from this "living" lost city with his partners.
