Qin Su, a criminal police officer, has been searching for the truth about his sister's disappearance for five years. For him, every case is not just as simple as solving a case, but more like facing his own pain again. This time, he took over a new disappearance case, but because of the irreparable trauma in his heart, he lost his way for a time.
