To raise money for her adoptive father's surgery, Su Heqing sells the dragon-and-phoenix jade pendant she has worn since childhood. The pendant is the token that can reunite her with the Shen family. After searching for their daughter for twenty years, the Shen parents see the pendant but do not rush to acknowledge her, secretly testing her character. Using her expertise in cultural relic appraisal, Su Heqing earns a place at the Shen family's auction house. She refuses bribes and special treatment, earning her position through her own performance. DNA confirms that she is the Shen family's long-lost biological daughter. After the reunion, the Shen family's adopted daughter, Shen Zhiyao, is manipulated into plotting a switch of the auction pieces. When the truth comes to light, Shen Zhiyao accepts responsibility, and the parties reach reconciliation. Su Heqing keeps her original name while cherishing the bonds she shares with both her adoptive and biological parents.
