The credits fade onto a blind man tapping his way down the sidewalk,he enters a dingy boarding house and hears a shot fired in one of the upstairs bedrooms. A door opens from audience POV. A man tumbles out of the door and falls, slides and slithers down two flights of stairs and is dead when he hits the bottom. Then follows nearly 100 minutes of flashback and flashbacks-within-flashbacks about a veteran returing from the war, tired and disillusioned, only to find that he girl he loves has lied to him about her relationship with another man, and that man is sadistic, boastful and tauntful.
