In the joint guard area at the border of Panmunjom, one day, North Korean soldiers (played by Shen Hejun) in the outpost were killed by bullets from unknown sources, triggering a shootout between the two sides. The most suspected killer was South Korean soldiers who were also on the border, but the South Korean side accused North Korea of mediating the incident first, and both sides believed that their opponents should be held responsible. In order to resolve this headless case, the North and the South agreed that a neutral country would conduct the investigation and coordination. Swiss South Korean girl Sophie (Lee Young-ae) is sent to investigate the incident. Lee Soo-hyuk (Lee Byung-hyun) on the South Korean side remains silent, while Wu Jingbi (Song Kanghao), a survivor on the North Korean side, shows hostility. Things are complicated and confusing. With a deeper understanding, Sophie found that there was a hidden inside story, and there was someone else at the scene.
