The Gu family's rain shelter, built for their own use, is reported by their neighbor, the Zhou family, and ruled an illegal structure. They are fined 5,000 yuan and ordered to dismantle it themselves. Gu Sui, the female lead, refuses to get caught up in personal grudges. Instead, she breaks with traditional village customs and launches an agricultural machinery harvesting service with transparent prices and a fixed booking schedule. Relying on their past relationship, the Zhou family refuses to sign up and insists on jumping the queue. Their privately hired, non-compliant harvesting machinery is seized during an inspection. Then a torrential rainstorm hits, leaving ten mu of their corn flattened and rotting in the fields. The Zhou family spreads rumors and slander, only to be confronted with undeniable evidence. In the end, they publicly apologize and compensate for the losses. The story promotes a positive approach to life: human relationships need boundaries, and everything must be done with principles.
