Post-traumatic stress disorder manifests in many forms, among the harshest of which is visited upon the Vietnam War vet who must climb up from the depths of a living hell in Jacob’s Ladder (1990). Hitting the dirt every time a car backfires and taking Asian fast-food deliverymen hostage are child’s play compared with the open-eyed nightmare entrapping Jacob Singer. The New York City mailman gallantly shrugs off flashbacks to his first marriage, but the horned creatures that attempt to slay him in the subway are not so easily put aside. And then there are the unscheduled visits from his long-dead young son. Life back in the world gets so rough, reenlisting starts looking good.
