Forensic doctor Chen Yan is rational and calm, specializing in solving bizarre murder cases. He believed in science but not in ghosts and gods, but during the autopsy he saw the female figure in red in the eyes of the deceased. Serial cardiac arrest cases occur frequently, and the deceased all die of extreme fear. A colleague disappeared, a white shadow was found on the surveillance camera, and the body left strange tooth marks. He was forced to contact the psychic Wang Po and saw a resentful spirit demanding his life for the first time. As the investigation deepened, a case of corpse burning thirty years ago came to light, and the cult's "human sacrifice" lurked in the shadow of the city. He went from watching indifferently to being haunted by resentful spirits, and was surrounded by dangers. In order to find out the truth, he learned spells, entered the underground palace, traveled through time and space, and stepped into the gap between Yin and Yang step by step. Reality and supernatural intertwined, and he finally became a "living judge" wandering the underworld.
