chunk: Barbra (Judith O'Dea) and Johnny Blair (Russell Streiner) drive to rural Pennsylvania for an annual visit to their father's grave. Barbara is attacked by a strange man (Bill Hinzman). Johnny tries to rescue his sister, but the man throws him against a gravestone; Johnny strikes his head on the stone and is left unconscious. After a mishap with the car, Barbara escapes on foot, with the stranger in pursuit, and later arrives at a farmhouse, where she discovers a woman's mangled corpse. Fleeing from the house, she is confronted by strange menacing figures like the man in the graveyard. Ben (Duane Jones) takes her into the house, driving the "monsters" away and sealing the doors and windows. Throughout the night, Barbra slowly descends into a stupor of shock and insanity.
