Geschwader Fledermaus(1958)

An American transport squadron led by former General Lee supports the French colonial army in Vietnam in return for high pay. Originally their mission was only to help the wounded, but as the advance of the Vietnamese liberation army puts the French under increasing pressure, they also fly ammunition - in return for even more money and in defiance of international law. Chief pilot Bryk refuses to fly, secretary Flessy becomes the unscrupulous general's mistress after one lover after another fails to return from a mission, and the rest of the squadron is shot down during an ammunition flight. The French army shows up at the camp to arrest the interpreter Thao for espionage. Bryk rescues her and flees with her to the liberated part of Vietnam.
