489 Years is transcribed according to the testimony of a former soldier in South Korea, Kim. It gives us access to the DMZ, and makes us immerse in the heart of the personal memory of a soldier. He tells us his experience in a research mission and the amazing discovery he made in the field full of mines (mines laid by South Korea with no record of where they were placed). He speaks of a place where people are forbidden, a place where nature has totally reclaimed its hold.
