Wu Jianfeng, deceived by his mother, mistakenly believed that his elder sister Wu Lan had taken the money and eloped twelve years ago. When his nephew Haohao came to borrow two thousand yuan for tuition fees, conflict erupted. Wu Jianfeng checked the bank transaction records, exposing the truth: his mother had intercepted the blood-and-sweat money that Wu Lan had bitterly earned to support his studies and entrepreneurship in order to curry favor with Li Dayou and his son, and had also spread rumors to slander the siblings. In the end, the siblings cleared up their misunderstandings, cooperated in business, and walked the path toward wealth.
