Based on the long running play by Jang Jin, the story is set in Korea during the Korean War in 1950. Soldiers from both the North and South, as well as an American pilot, find themselves in a secluded and naively idealistic village, its residents unaware of the outside world, including the war.

Jae-Hyeok (Kim Nam-Gil) lives with his mother (Kim Young-Ae), his sister-in-law (Moon Jeong-Hee) and nephew Min-Jae (Bae Gang-Yoo) in a small Korean town. He is dating Yeon-Joo (Kim Joo-Hyun), while working at the local nuclear power plant. Meanwhile, Pyung-Sub (Jung Jin-Young) works at the same nuclear power plant. He is worried about conditions there, but nobody in the government listens to him. An earthquake strikes the small town where Jae-Hyeok lives and causes explosions at the nuclear power plant. The situation quickly spirals out of control, leading the entire nation to panic. To prevent another nuclear disaster, Jae-Hyeok and his co-workers return to the nuclear power plant.
