Joint Security Area (2000)

In the joint security area on the border of Panmunjeom, one day, a North Korean soldier (played by Shin Ha-kyun) in the post was killed by an unknown bullet, triggering a gun battle between the two sides. The most suspected murderer was a South Korean soldier on the border, but South Korea accused North Korea of stirring up trouble in the first place. Both sides believed that their rivals should be responsible.
