Once Before I Die (1966)

When the heat of the jungle and the hell of war cross paths

Stranded behind enemy lines when the Japanese attack the Philippines in late 1941, Lt. Bailey must lead a group of soldiers and their families (including Bailey's curvaceous fiancée Alex) to safety and the streets of Manila. During the perilous trek Alex befriends a virginal young soldier whose only desire is to have sex once before he dies.
