Page "Jacob's Ladder (film)" Paragraph 2

The film then shifts back and forth from Vietnam to Jacob's memories ( and hallucinations ) of his son Gabe and ex-wife Sarah, and to his present ( set in 1975 ) relationship with a woman named Jezzie while working as a mailman in Brooklyn, New York City.

During this latter period, Jacob faces several threats to his life and experiences grotesque hallucinations.

It is also revealed that his son Gabe was hit by a car and killed before Jacob went to Vietnam.
