After transferring to a new school, Xia Xinghe, the true heiress of the richest family in the country, unexpectedly catches her boyfriend of five years, Wang Haoqian, being intimate with Shen Wei, who is pretending to be her. The two humiliate her and cruelly break up with her. To get close to Wang Haoqian, Shen Wei steals Xia Xinghe's dormitory key card, constructs a fake heiress persona, and frames Xia Xinghe for stealing a chip design blueprint. Drawing on her own talent, Xia Xinghe immediately produces an even better design to prove her innocence, only for the pair to turn around and accuse her of plagiarism. Xia Xinghe plans to use her birthday party as an opportunity to expose Shen Wei and Wang Haoqian's lies once and for all, right in front of her father. A showdown over identity, truth, and revenge is about to begin.
