On the eve of her wedding, Cheng Wan's future mother-in-law takes her bank card, which holds Cheng Wan's savings and dowry, under the pretext of managing the young couple's finances. Her fiancé, Gu Tianliang, not only sides with his mother but also hits Cheng Wan during their argument. Cheng Wan immediately fights back, calls off the wedding, and resolves to recover the 400,000 yuan that rightfully belongs to her. As the financial records come to light, her fiancé's younger brother is exposed for using the money to buy a luxury car, while her sister-in-law has been taking funds to cover her own family's debts. The Gu family even tries to seize the marital home, cause trouble at her workplace, and stage a fake wedding banquet to collect gift money and fill their financial hole. Armed with evidence, Cheng Wan strikes back against each of them, pursues her money through legal means, and refuses to reconcile. In the end, she gets her assets back and reclaims control over her own life.
