When the weak and orderly man meets Lin Wanqing, a materialistic female detective, one is forced to catch ghosts and the other is forced to believe in ghosts. From the girl in red to the Wangchuan pawnshop, he has grown from a "prey" at the mercy of ghosts to a "hunter" who can control hundreds of ghosts; from cold interrogation to risking his life to protect him, she has become his most solid backing. When urban legends intertwine with the grudges of their fathers, they join forces to fight against the evil organization "Gui Xuhui" and uncover the hidden truth!
