Late one night while pursuing a fugitive, Jiang Yan is unexpectedly handed an old newspaper from twenty years ago. An inconspicuous missing-person case in its pages points to the truth behind his father's death in the line of duty. Meanwhile, reporter Wen Qing is investigating the same lead, forcing the two to work together. The old newspaper is tied to a deal and a family's secrets. As an elderly forensic pathologist, a crime boss, and others get involved, the cold case comes back to life. Jiang Yan and Wen Qing dodge their pursuers as they piece together the truth, only to discover that one of the people they trust is a mole. Who is lying? Why did that newspaper find its way into his hands? Every step brings them closer to the truth, and deeper into a trap.
