Fourteen years ago, Sophie Sterling suffered head trauma and a broken leg while saving her kidnapped daughter, resulting in total amnesia. Migrant worker Thomas Fisher found her and renamed her Sophie. Fifteen years later, Victoria Sterling, now CEO of Sterling Group, is still searching for her mother when she meets Sophie, who is seeking workplace injury compensation. Denied the payout, Sophie also endures constant bullying from her mother-in-law and brother-in-law. Later, Sophie regains her memory. When Victoria goes blind, Sophie donates her cornea and leaves quietly. Ultimately, they reunite, and the mother-in-law and brother-in-law face justice.
