In order to prove his innocence and pursue the truth, he had to join forces with Su Qing, a smart and capable female police detective who carries family secrets. In the fog-shrouded city of sin, the two grew from mutual suspicion to mutual trust, and jointly faced a huge criminal network hidden in the shadow of the city. Behind every case, there is a more surprising secret, and they themselves seem to have already been part of the chess game.
