The most frightening thing about Jacob Singer's nightmare is that he isn't dreaming.

Divorced Vietnam veteran turned postman Jacob Singer (Tim Robbins) is disturbed when he begins to be plagued by bizarre and violent hallucinations, both of the family he has abandoned and a bloody battle he could not previously remember. So strong are the images that the line between past and present, real and unreal, begins to dissolve. Desperate for help, Jacob turns to his ex-wife, Sarah, and chiropractor Louis (Danny Aiello).
