District 820

The 820 area lies on the border of two Koreas. At a military base in South Korea, Lt. Kwon and her three subordinates have been conflicting for several days. When they start the last patrol, feeling with the tension among themselves, they hear a gunshot. Meanwhile, Joon-im and her photography club members get lost and walk into the 820 that is restricted for the civilians. They meet Lt. Kwon's party, and Kwon orders the soldiers to escort the civilians out of the area. As they head to the perimeter, soldiers disappear one by one, and the remains feel confused and terrified.
