Before Oldboy and The Handmaiden, visionary filmmaker Park Chan-wook helmed this gripping tale of deceit, misunderstanding and the senselessness of war. Gunfire breaks out in the demilitarised zone between North and South Korea, leaving two North Korean soldiers dead while a wounded South Korean soldier (Lee Byung-hun) flees to safety. With the tenuous peace between the two warring nations on a knife-edge, a neutral team of investigators, headed by Swiss Army Major Sophie Jean (Lee Young-ae, Lady Vengeance), is dispatched to question both sides to determine what really happened under cover of darkness out in no-man's land.
