Abandoned by her older sister as a child, Grace grows up to fulfill her biological father's mission and save her adoptive mother. She marries into the Forrest family as a substitute, a family she considers her enemies. For three years, she endures her husband's neglect and the constant humiliation from her ex-boyfriend, secretly gathering evidence of money laundering. When her contract expires, she reveals her status as heir, divorces her husband, and retaliates—sending her enemies to prison, bringing the con artists to justice, and ultimately inheriting the empire, making those who wronged her pay the price.
