Shen Yan, former head of the major crimes squad, returns to the police force as a consultant, still haunted by the “Nightingale Serial Murders,” which went unsolved for three years. One stormy night, a bizarre murder takes place in Jiangcheng. The victim is found kneeling, with a black nightingale feather left on their chest. The clues are almost identical to those from the old case. Su Qinghe, an independent forensic examiner, is invited to the scene.
