During the Korean War, there was a remote mountain village called Dongmo Village near Gangwon Road. The people there were cut off from the outside world and lived a self-sufficient life, and they didn't even know that there was a war outside. The South Korean national army's Bian Xuan Zhe (Shen Hejun) and health worker Wen Shangxiang (Xu Zaiqing) come to Dongmo Village because of escaping from the camp and falling behind. At the same time, the Korean people's Army's Li Xiuhua (Zheng Zaiyong) and veteran Zhang Rongxi (Lin Helong) and young soldier Xu Zeji also went to Dongmo village. Prior to this, because of the plane crash, the American pilot Captain Smith (Stephen Teshuller) also came to the village. When the soldiers of the two sides met, there was tension, and then the tense confrontation gradually calmed down and did not invade each other, but there was still a lot of hostility. In contact with the simple villagers, the soldiers got used to the peaceful life in Dongmo village. Later, even when the war fell on the village, the soldiers on both sides decided to take on the task of defending Dongmo village.
