Lin Mo, a trainee lawyer, hides a secret beneath his refined, gentle exterior: he is heir to an ancient mystical tradition, with a deeply calculating mind to match. He moves between modern law and ancient arts, divining cause and effect and commanding the forces of feng shui, listening for thunder in the silence.
When Chen Mo, captain of the city criminal investigation squad, loses faith after confronting a series of supernatural murders, and Su Xiaowan, a forensic doctor with yin-yang eyes, hears whispers from another world, they are drawn into Lin Mo's game. In the depths of an antique shop, Old Zhou leisurely brews tea, watching his disciple make his moves.
Meanwhile, in the shadows, Shen Yuan, the chief of the Netherworld Bureau, is weaving an all-encompassing web, intent on tearing apart the boundary between yin and yang. In this ultimate contest between light and darkness, Lin Mo smiles as he makes his move. He turns the mortal world into a game board, and takes on ghosts and gods alike.
