Three years after her mother's death, Shen Yu discovered that her collection of wedding rings and manuscripts had been secretly pawned by her stepmother, Lin Sulan. He remained calm and used a hidden camera to record the whole process of her stealing and selling her belongings and forging her will. When the video was exposed, Lin Sulan accused him of being insane, and even his most trusted housekeeper and sister fell silent. He thought he was seeking revenge alone, but unexpectedly it led to the conspiracy of a lawyer, the betrayal of a private detective, and the belated awakening of his sister. A tug-of-war about memory, inheritance and redemption breaks out in the cracks of morality and law.
