Unemployed A Jie prepares to open a barbecue restaurant with funding from his father-in-law, Old Li. Old Li takes out three million in retirement savings and entrusts his son, Li Ming, to transfer it. However, out of greed, Li Ming keeps it for himself to pay off gambling debts. Left with no choice, A Jie sells his house and takes out online loans to finally open the restaurant. Old Li brings his veteran comrades to support the business and pay via QR code scan, but Li Ming secretly switches the payment code, intercepting over 500,000. Mistakenly believing his father-in-law was eating and drinking for free, their argument is maliciously edited, causing A Jie to shoulder a bad reputation. After the truth comes to light, Li Ming sinks deeper into gambling, defrauding a total of 3.6 million before and after. The family gathers evidence to seek legal protection, and ultimately Li Ming is imprisoned for fraud and gambling. A Jie and Xiao Ya keep the barbecue restaurant, pay off the online loans, and the two families resolve their estrangement.
