Lu Zhaoning, the sole heir to the Lu Group, returns from overseas. Just after getting off the plane, she is deliberately framed by her future sister-in-law, Lin Yu, who falsely accuses her of losing an extraordinarily expensive necklace. She is even thrown into a fountain by security guards. Lu Zhaoning initially intends to reveal her true identity, but the arrogant and overbearing Lin Yu refuses to believe her. Even more astonishingly, her adoptive brother, Lu Yuzhou, is convinced that Lin Yu is the lifesaving benefactor who rescued his younger sister years ago. Investigating in secret, Lu Zhaoning discovers that the real benefactor is Lin Yu's half-sister, Lin He, and that Lin Yu stole the jade pendant to falsely claim the credit for saving her. At the wedding, Lu Zhaoning publicly reveals all the evidence and exposes Lin Yu's lies. Meanwhile, an ambitious shareholder, Huo Zheng, seizes the opportunity to stir up trouble and attempts to seize control of the company.
