In the 1980s, in Huaihua Village, Zhao Dajiang, who understands agricultural machinery technology, returns to his hometown. Together with Teacher Wen, who has put down roots in the countryside, he takes the lead in organizing the villagers to establish an agricultural machinery mutual-aid group. Drawing on local farming practices, everyone experiments with new ways to use agricultural machinery and shares maintenance and care experience, gradually improving their fieldwork methods. Thanks to everyone's careful efforts, the wheat fields flourish and harvests steadily increase. As Zhao Dajiang and Wen Xiulan work side by side to cultivate the land, the villagers help one another, and everyday life is filled with the simple warmth and harmony of rural living, painting a picture of a peaceful and fulfilling countryside life.
