Guayuetai is a mountain village located in the mountains. Guayue Road is rugged and difficult to travel, which not only affects the development of Guayuetai, but also brings many difficulties to the lives of the villagers. In order to solve this dilemma, under the support and leadership of the village party branch, Ma Chunxiu, the captain of the Guayuetai Iron Girl Commando, and Yu Dahe, the captain of the militia, organized all the villagers to repair Guayue Road. However, due to Ma Chunxiu's wrong decision, the unauthorized blasting caused a landslide and the construction of the mountain road was forced to stop. In order to raise funds for the continued road construction, the village party branch decided that Ma Chunxiu and Yu Dahe would lead the villagers to work in the city. Ma Chunxiu and Yu Dahe, who went to the city, led the villagers to fight for their own business. Just when the fund raising was about to be completed, the feelings of Ma Chunxiu and Yu Dahe quietly changed. Sisters Wang Shuiling and Su Lirong who went to the city together also made their own life choices in their growth. In the end, with the full support of the local government, party members and cadres took the lead in fighting, and Guayuetai finally had a sky road connecting to the outside world.
