Siblings Barbra and Johnny drive to a cemetery in rural Pennsylvania to visit their father's grave. Their car radio goes off the air due to technical difficulties. As they are leaving, a strange, ashen-faced man wearing a tattered suit kills Johnny and attacks Barbra. She flees and takes shelter in a farmhouse, but finds the woman who lived there dead and half-eaten. She sees a multiplying number of strange ghouls, led by the man from the cemetery, approaching the house. A man named Ben arrives, secures the farmhouse by boarding the windows and doors, and drives away the ghouls with a lever-action rifle he finds in the closet and with fire, which he previously discovered the ghouls fear.
