Chen Fan, a small gangster who lives on the streets, fights fiercely, collects protection money, and does nothing all day long. He has a neighbor who gives him a headache - the seemingly honest and honest bun shop owner Wang Defa. This neighbor gets up at four o'clock every morning to steam steamed buns, greets him with a smile, and often gives him steamed buns to eat. Chen Fan occasionally orders steamed buns from Wang Defa Steamed Bun Shop for breakfast and feels that this neighbor is really a good man. Until one day, Chen Fan accidentally discovered that three walls of cash were hidden in the basement of Wang Defa's bun shop - at least 200 million. What's even weirder is that this seemingly harmless bun shop owner is actually the financial backer behind the largest underground force in the city, with eight lives on his hands. When Chen Fan accidentally obtained Wang Defa's account books, a suffocating game of wits began between him and this seemingly honest neighbor. Every time Chen Fan thought he had caught Wang Defa's hand, he would be shocked by this "honest man"'s reversal. What made Chen Fan even more devastated was that he found that he actually had an unexplainable affection for this murderous neighbor.
