Night of the Living Dead

When Barbra visits her father's grave with her brother Johnny, they are suddenly attacked by a strange pale man. Barbra is able to save herself in an abandoned farmhouse nearby, where Ben also arrives a little later.
In the cellar they discover more people holed up there: The couple Tom and Judy as well as Harry and Helen Cooper with their daughter Karen.
From the news, they learn of a deadly epidemic that is spreading rapidly, resurrecting the recently deceased as the flesh-eating undead. The barricaded and increasingly besieged country house becomes the last refuge in the relentless fight against the zombies.
