A cursed bell, a murder that has been silenced for hundreds of years, and a pursuit across Yin and Yang.
When folklore editor Shen Mo picked up the weird pocket watch with the name "Su Wanqing" engraved on it late at night, he didn't know that he had opened a door to hell.
The female student from the Republic of China who followed him like a shadow in the mirror, the knock on the door that sounded in the middle of the night, the old-fashioned leather shoes that appeared out of thin air at home... The ancient resentment was like a vine, tightly wrapped around his life. Only those "yin eyes" awakened by fear can glimpse the truth in the darkness.
At the same time, in order to fulfill her grandmother's last wish, documentary director Lin Wan vowed to find out the mystery of the unjust death of her friend Su Wanqing. She didn't believe in ghosts and gods, she only believed in the lens in her hand, until she witnessed with her own eyes that the camera recorded horrific images that could not be explained by science.
Two fateful trajectories intersect due to an old case. The whispers of dead souls in an abandoned campus, the deadly pursuit of evil organizations, the "Bell Tower of Resentful Bones" recorded in ancient books... As the investigation deepened, they discovered that Su Wanqing's tragedy was not the end, but the beginning of a dark ritual that lasted for nearly a hundred years in the name of "rebirth" and was actually "building a platform with bones".
The bell is about to ring again, and the boundaries between yin and yang are becoming increasingly blurred.
In this competition between humans and ghosts, good and evil, Shen Mo and Lin Wan must join hands to find the last chance of survival between the whispers of resentful spirits and the traps of reality.
The truth is often more frightening than ghosts.
What is more difficult than destroying an evil spirit is saving a soul swallowed by hatred.
