This film allows a senior officer of the US Air Force who was shot down in the Vietnam War to witness the bloody battlefield in Vietnam and reflect on this war. Hambleton (code name Bat 2 1) chatted with the observer pilot (code name bird dog) and said that he had been commanding operations at high altitude, and a command could destroy a considerable number of enemies, but he never thought that the war on the ground was completely different from what he imagined in the air. 1 and when he accidentally killed a Vietnamese farmer who was eager to defend his country, he exposed the whole Vietnam War questioning view. The film was adapted from a story in the late Vietnam War and was shot by TV director Peter Markle. Although it is a low-cost movie, the rhythm, textual research and tension of the plot are surprising.
