DMZ, the tomb where underserving deaths lay.
An education officer who was dispatched died after a gunshot went off in the dead of night. At the same time, deserters flee to the DMZ in the access control zone, and the 3rd platoon is urgently deployed to the DMZ search operation. There, the crew sees an unidentified soldier, not a deserter or a search crew.
And the unknown death relay begins…It all started that day!
