selfish and argumentative husband; his wife Helen; their daughter Sarah, who was bitten by a zombie and has fallen seriously ill; and teenage lovers Tom Bitner and Judy Rose Larson. The group is divided over what their next course of action should be. Harry believes everyone should retreat to the cellar and barricade the door to wait for the authorities. Ben thinks the cellar is a "death trap" and that they would be better served fortifying the house, which at least has alternate escape routes, and Barbara suggests that the group should simply leave the house on foot after she notices the zombies' limited mobility.

Both Ben and Harry are badly wounded, and Barbara shoots Sarah. Harry retreats upstairs to the attic, while Ben makes his way to the cellar, where he shoots a reanimated Helen. Ben gradually goes into shock, and after realizing the gas key
