"GP506" is Korea's first front-line suspense search film. For the first time, the demilitarized zone, completely cut off from the outside world, has been brought to the screen, bringing attention to this place that had been almost forgotten after the war. Most of the background in the film is the outpost, there are no traces of external infiltration, no enemy barbed wire, no paranormal phenomena, but only through natural theories to promote the development of the plot, containing the meaning of examining society with military themes.
On the night of the rainstorm, 20 of the 21 sentries were killed and one unconscious at a front-line guard post located in a demilitarized zone where no one is allowed to enter. In order to investigate the truth of the incident, the military sent a search team of 21 people to search. But the road was washed away by the torrential rain and the search party was trapped inside GP506.
The Ministry of Defense ordered Investigator Lew to lead a team to investigate, and specifically instructed him to find the chief of staff, the son of the chief of staff, from the body that had been killed. Investigator Lu was asked to end the search by 6 a.m. the next morning. But a new picture emerged, with only 19 bodies and one person surviving. But this man left no trace. GP is like a maze, and during the search, a living GP chief was accidentally found in the power room. However, he only asked for a return to his own team, and more and more suspicious signs appeared.
The search team included investigators who were known as elite dignitaries. At his wife's funeral, Roche received an order from the upper echelons to find the captain of the sentry guard among the corpses. The captain was the son of the chief of staff, and the matter was of great concern to the entire Ministry of Defense. The time given to Roche by the upper floor ended at 6 a.m.
New clues are being discovered all the time - 19 bodies have been recovered, and one is still alive. Nearly lost, the search party unexpectedly found the surviving team member, who was the captain of the special sentry post. However, the captain simply asked to return to the unit headquarters. For a moment, the whole incident was covered with a thick layer of fog ......
The captain who was found was actually a health officer from the original outpost. The veteran horse at the base went out to mow the grass, and he and his fellow team members all got sick strangely. Upon return, the virus is so brutal that even when the patient regains his or her senses, he does not remember the crime he committed. The captain was afraid that the leakage of the incident would endanger his and his father's careers, so he did not report it. As a result, after a firefight, the captain's command was sidelined. Soldier Ginger fears that the virus will spread to the world, so he kills his teammates after recording the evidence, and warns the others who break into the base to kill them as soon as they find a living person!
However, by the time the investigators realized that it was too late, the desperate soldiers tried to make up and abscond in vain in order to find a way out. In order to avoid the escalation of the situation, Luo Investigator cooperated with the military medical officer who conducted the autopsy together to mutiny of the soldiers, and he also gave his life. And the basement of the sentry was also reduced to ashes in the sound of **.
