In the autumn of 1984, provincial reporter Xu Zhiyuan is demoted to Yunhe Town and receives an anonymous tip claiming that four people have disappeared from the old Wang family residence in the west of town over the past three months, and that someone may be using “hauntings” to conceal the truth. The tip reopens the old wound of his father’s mysterious disappearance three years earlier.
As he investigates, he finds that something strange lurks in the old residence: bloodstains, eerie noises, and mysterious symbols keep appearing, while villager Li Dashan hides the truth. The feng shui master Zhao Wuye reveals that an “Yin Gate” lies beneath the residence, connected to the realms of Yin and Yang.
Xu Zhiyuan’s own “Taiyin constitution,” the silver lock and Book of Yin-Yang Secrets his mother left him, and clues in his father’s notebook all point to this Yin Gate. Meanwhile, tomb robbers plan to use a living soul to open the gate and seize its treasures. Torn between science and superstition, he faces evil spirits and a deadly pursuit as he searches for his family’s secrets and the truth behind the Yin Gate.
