The movie shows the decades-long conflict between Liu Shoushan, who has a dream of joining the party and is very affectionate and righteous, and Yu Jinshui, an old branch secretary of the Anti-American War Party, who has a deep war record, as well as the story of the young generation of grass-roots Party members and cadres, represented by the first secretary of the village, Sun Fang, who are working hard to change the poverty of their hometowns. Although the two generations have different personalities, they share a common ideal. The intense collision between them drives the story forward, which not only realizes the perfect closed loop of communication between the two generations, but also highlights the power of "love", which ultimately makes Niujiakuang Village a bright pearl in the process of rural revitalization in the new era.
