Twenty years ago, Kelly was abandoned by her lover Richard. Out of hatred, she secretly swapped her newborn daughter with the legitimate heiress Elisa of the wealthy Stirling family. Since then, Kelly’s biological daughter Olivia grows up arrogantly in luxury, while the real heiress Elisa endures poverty and harsh treatment at the bottom of society. Years later, grandmother Diana returns from abroad, uncovers the baby-switch truth step by step, and helps Elisa regain her identity and inheritance. All villains who committed evil deeds are severely punished in the end.
