Ten years ago, two "accidental" falls from the building laid bloody foreshadowing; three murder cases without a secret room, the black king, white elephant, and white rook were sacrificed one after another, the chess pieces were held in the palms of the deceased, and death symbols were all over the scene. Genius forensic doctor Su Qingyuan originally thought that the path to pursue the murderer would lead directly to the crazy rich man Gu Yanchen, but he discovered a shocking twist in his mother's belongings - his mother was actually a core member of a transnational smuggling group, and Gu Yanchen was just an abandoned piece on the chessboard! The white king's chess piece reappears, the smuggling network's fangs are exposed, every secret room hides a double trap, and every memory may be a fatal lie. When the truth intertwines with crime, Su Qingyuan must not only crack the 20-year-old smuggling secrets of the "Night Owl" group, but also face her mother's dark past. Who is the real chess player in this chess game that depends on life? Will the next chess piece to be sacrificed be herself?
