Yin Yijian, captain of the criminal investigation team, has a son named Yin Yifan. One night, while walking home alone after evening study, Yin Yifan mysteriously disappears in a village in the city rumored to be haunted, where the bones of a murdered girl have been unearthed.

From then on, an invisible hand manipulates him, forcing him step by step into an even deeper abyss. But there is far more to this than meets the eye...
