Aunt Su takes out her savings of one million to support her daughter-in-law Wanwan in opening a restaurant, and brings friends to spend money and show support. Unexpectedly, Wanwan publicly accuses her of eating and drinking for free, and even mortgages her parents' house for the business. Why hasn't the restaurant received a single cent of the money that was clearly paid, and where did the million-yuan startup capital originally given to the daughter-in-law go? A mother-in-law and daughter-in-law dispute accidentally exposes a secret meticulously concealed by husband Su Yang. As transfer records, false receipts, and marital betrayal surface one after another, two women who used to complain about each other decide to join forces to investigate. Faced with the tug-of-war between family affection and interests, can Wanwan keep the restaurant, recover the cheated money, and find family members truly worthy of trust?
