During the Korean War, in a remote small mountain village called "Dongmo" near Gangwon-do. The people there are cut off from the outside world, living a life of self-sufficient hideaways, and they don't even know the wars going on outside.
South Korean army Pyo Hyun-chulis a deserter who hates war so much that he even thinks of suicide. Fortunately, Moon Sang-sang, a timid hygienist who was left behind, saw that Pyo Hyun-chul did not commit suicide. They walked together and came to Dongmo Village., a captain of the Korean People's Army, Jang Rongxi, a veteran soldier, and Xu Zeji , a young soldier, also came to Dongmo Village. Before that, because the plane crashed, the American pilot Captain Smithalso came to Dongmo Village.
When the soldiers of the North and South Korean armies met, the swords were drawn, and the North Korean soldiers held grenades because there were no more bullets in their guns, ready to detonate, while the South Korean soldiers pointed their guns at them. Among them, is a group of simple villagers. The villagers thought they were carrying out some kind of ceremony and laughed as usual in the middle. After a night of confrontation, Wen Shangxiang detonated a grenade because he was so sleepy. The grenade was thrown into a granary not far away, and the corn in the granary turned into popcorn.
The confrontation between the two sides gradually calmed down and did not invade each other, but there was still a lot of hostility. Once, a wild boar invaded the villagers. North and South Korean soldiers and American Smith worked together to subdue the wild boar. In the evening, everyone ate wild boar, and the hostility slowly disappeared.
Gradually, the soldiers became accustomed to the life of working here at sunrise and resting at sunset. But the war is still going on outside, and it will soon come to this small village. Because of the crash of Smith's plane, the US military suspects that there is a North Korean military base here. Send planes to bomb.
Seeing that there is no concept of war at all, the simple and kind-hearted villagers will be slaughtered by war. Soldiers who have been away from the battlefield for a long time decided to return to the war and take on the task of defending the village.
