Xu Liunian, a young man returning to his hometown, has just renovated his old family home into a cozy courtyard residence when his neighbor, Du Zhenhai, builds a pigsty right against his courtyard wall. The stench overwhelms his flowers, and the villagers watch the spectacle, convinced he has no choice but to put up with it. But Xu Liunian remains silent and fills his courtyard with mint. No one expects the mint to make the pigs addicted to its stimulating effects, leaving his neighbor panicking first. Du Zhenhai escalates his harassment step by step, spreading salt, pouring chemicals, and blocking the door with a knife. Xu Liunian fights back with surveillance footage, mint mist, and a trending online topic. At last, the pigsty comes down, while mint becomes a sensation. From being targeted by the entire village to becoming a farm business partner, he turns a battle with a malicious neighbor into a comeback through rural entrepreneurship.
