Whilst surveying the outside of the house, the teens find a gravestone belonging to a woman named Abigail Leatherbee.
Downstairs, the rest of the group discover that the windows have also been locked shut, and they find themselves unable to break them even when using heavy objects.
After reuniting with Jamie and learning of Mark's fate, the gang decides to gather weapons and wait until Joey returns so he can go get help.
When a window on the third floor of the house opens, Joey grabs a ladder and climbs up to it, only for the old lady to appear and kill him.
As the teens search the house for the old lady, Steve inadvertently gets separated from the rest of the group and encounters an undead Joey, who tells him that he and the others won't be able to escape.
Having overheard his death, Bob becomes determined to find the old lady and kill her, although Jamie insists that they focus on trying to escape.
Later, whilst exploring the basement, Jamie and Linda find a newspaper article about Abigail Leatherbee, the mysterious old woman whom was also a former owner of the house.
As the night progresses, Ron and S manage to defeat the undead Steve and Bob before encountering Abigail as they try and make their escape.
