Qinghe Village pools its money to build a road. Xu Jianjun contributes 5,000 yuan, but the road is deliberately rerouted around his house. The village chief and his relatives fabricate a boundary dispute to bully him. His daughter, Xu Zhixia, returns to the village and raises the courtyard wall. Using the homestead ownership documents, she uncovers the truth and reclaims the road, ensuring those responsible are punished. Later, she discovers that the market for locally grown pecans is being deliberately monopolized. She takes the lead in establishing a cooperative to standardize production and sales. At a pecan appraisal competition, she exposes her rivals' adulteration and fraud, building a strong reputation for the local pecans. When a dispute over wasteland breaks out, Xu Zhixia convinces everyone to secure the land with her long-term development plan. The towering wall that once symbolized their fight for justice becomes part of the village's transformation. Xu Jianjun regains his dignity, while the village achieves both industrial development and justice.
