Jacob's Ladder

On October 6, 1971, an American infantryman, Jacob Singer, is with the 1st Air Cavalry Division, deployed in a village in Vietnam's Mekong Delta, when his close-knit unit comes under sudden attack. As many of Jacob's comrades are killed or wounded, others exhibit abnormal behavior with some suffering catatonia, convulsions, and seizures. Jacob flees into the jungle, only to be stabbed with a bayonet by an unseen assailant.
