Xu Sijia, the eldest daughter of the Xu family, married the poor boy Meng Zhiheng and helped him build his business. After marriage, she took care of his so-called widowed mother Zhang Xinghua and isolated sister Lin Cha for five years. When her executive assistant secretly reported a hidden compartment behind the study's oil painting, Xu Sijia uncovered the scam: Zhang Xinghua is Lin Cha's biological mother, Lin Cha is Meng Zhiheng's mistress, and the child in her belly is also Meng Zhiheng's flesh and blood. Meng Zhiheng also transferred 200 million in assets and forged 5 million in debt, intending to leave her with nothing. Joining forces with lawyer Ji Shiyu, Xu Sijia publicly exposed everything at the birthday banquet, set up traps in business battles to defeat and counterattack the villains, ultimately sending the criminals to justice, reviving the Xu Group, and finding true love with Ji Shiyu.
