In 1985, Chen Qingshan returns from the south to Chen Family Village with a fortune. He should have been welcomed home in triumph, but instead, he publicly reopens the old case from fifteen years ago, when his father, Chen Shouyi, was falsely accused of stealing money. From the ancestral hall's account books and a wooden chest in an old well to secret ledgers at the supply and marketing cooperative, layer upon layer of evidence exposes the corruption of Wang Futian, Chen Wanhe, Lu Guochang, and others. Using a factory project as his plan, Chen Qingshan clears his father's name and helps the entire village settle its accounts and build roads. But he discovers that the real mastermind is still waiting for him in Nancheng.
