After her son-in-law lost his job, he wanted to open a restaurant. Father-in-law Lin Hai took out six hundred thousand to support him and continuously brought friends to spend money and show support. But three months later, the son-in-law publicly accused his father-in-law of not paying for his meals, even claiming that thirty thousand in dining fees had completely disappeared. Lin Hai was shocked because he clearly paid every single bill. After an argument, the two discovered that the six hundred thousand opening funds and the thirty thousand consumption funds had all flowed into a strange account. As the investigation deepened, fake QR codes, bogus purchase orders, and duplicate payments were exposed one after another, and the person he trusted most gradually surfaced. A truth investigation regarding money, trust, and family affection officially begins.
