Watching R-Point and so far so good.
“The film is set in 1972 during the Vietnam War. A group of South Korean soldiers from Battalion 53 fail to report back from a strategically important island 150 kilometers south of Saigon referred to as R-Point. The soldiers have been missing for 6 months and are presumed dead, until a shortwave radio transmission from R-Point is received from the missing soldiers. The transmission continues at irregular intervals over the next 3 months, repeating the same message - “Donkey 30, Butterfly, do you copy? Donkey 30, Butterfly, do you copy? We are dying…” This prompts HQ to dispatch a search-and-rescue party out to find the missing men, even though the sole survivor of the team insists that he saw all of them die and that he was the one who collected their dog-tags.”
