At her eighteenth birthday banquet, Lin Zhixia is pressured by her own mother to give up her multimillion-yuan inheritance for the sake of her stepson, Zhao Jiayou. Using an old account book left by her maternal grandfather, she discovers that her mother has already misappropriated her tuition fees, rent money, and trust fund. Her father, Lin Yuanshan, who left home three years ago carrying the stigma of a factory fire, returns and joins forces with her to recover the money and expose a forged will. Their investigation gradually uncovers the truth: her stepfather deliberately set the fire to seize the family fortune. Facing emotional blackmail from relatives and a relentless public backlash, father and daughter use evidence to reclaim justice. What she wins back is not just her inheritance, but also the right to decide her own future.
