Hedong, a medical university graduate, was born with the ability to see "shadow people". Due to a strange hospital haunting incident, he was forced to return to his hometown in the Northeast to inherit his grandfather's shamanic mantle. He originally did not believe in ghosts and gods, but he encountered bizarre events one after another in Heishui Village, such as "Yellow Pizi seeking a title", "Old tree becoming a spirit" and "Ghost market appearing". He gradually realized that shamanism is not superstition, but an ancient wisdom that communicates between humans, spirits and nature.
As the investigation deepens, Hedong discovers that his grandfather's death is related to a movement to destroy the Four Old Ages in the 1970s. The mass graves underground in the countryside are still full of resentment, and the developer's digging of the dragon's veins has triggered a night march of hundreds of ghosts. On the night of the Ghost Festival, he danced the sacred dance and played the sacred drum to save the souls of the dead, but unexpectedly revealed the tragic past of the shamans who used their lives to quell evil during the Anti-Japanese War.
In the end, Hedong competed with overseas treasure stealing gangs in the secret realm of Changbai Mountain to fight for the shaman's sacred objects and prevent the evil god from coming to the world. He understood that the shaman's mission had never disappeared, but had just changed into a different form - healers save people, and shamans save souls. He chose to stay in the Northeast, establish a modern shamanic cultural center, and find a balance between science and faith between man and nature.
