[3] One year after the deaths of their daughters Addie and Jade, Albert Poe is ready to move on from the loss while his wife Rose is still stuck in her grief, baking a birthday cake for the girls and speaking of them in present tense.
Talking to her therapist Dr. Connor, Rose describes seeing evidence that her daughters are alive and mentions finding a manuscript about demons in the attic.
Albert lists the house for sale but dismisses the manuscript as religious propaganda until he discovers a tape recording showing that their daughters were coaxed onto the roof by an unseen entity, only to fall to their deaths.
Albert and Rose are later chastised by a strange woman named Nebula, who appears in their home and states that if they had properly researched the house their daughters would still be alive.
A scene then shows that a local realtor named Fred is plotting with Nebula to force Albert and Rose out of the house, but that they must now allow events to play out on their own.
Twenty-five years prior to the deaths of Addie and Jade, Donovan murdered two Girl Scouts in the house in order to rid his body of demons.
