Taking an Audi car that has sunk into the reservoir for ten years as a guide, the mystery of fate spanning twenty years is revealed. Bronze lighters are linked to a series of unsolved cases such as chemical plant explosions, engineers' bizarre "suicides", factory directors' mysterious disappearances, and the "accidental" deaths of many gangsters. Chen Mu, the deputy captain of the criminal investigation, discovered that behind all this was the struggle and silence of a suffering woman, Su Xiaomei, in a desperate situation. It was also a secret revenge jointly woven by her brother and her husband's comrades. When the truth emerges, the boundaries between law, justice and private redemption become blurred, but the lighter sealed in the evidence room still shines with a weak and undying light.
