Night of the Living Dead (1968)

A disparate group of individuals takes refuge in an abandoned house when corpses begin to leave the graveyard in search of fresh human bodies to devour. The pragmatic Ben does his best to control the situation, but when the re-animated bodies surround the house, the other survivors begin to panic. As any semblance of order within the group begins to dissipate, the zombies start to find ways inside. One by one, the living humans become the prey of the deceased ones.
