Eve watches Thomas and his family come inside and becomes more convinced that Thomas really did grow up in the house when he opens the coat closet without thinking. While Paige quietly judges the house’s condition, Eve reflects on how she and Charlie bought the isolated Oregon property because it was cheap despite its severe disrepair and their financial pressure. Thomas introduces Paige, Jenny, Kai, and Newton, and Eve quickly notices the family’s internal dynamics: Jenny is curious and devoted to her father, Kai is smug, and Newton is anxious and passive.

As Thomas begins the tour, he points out details from his childhood, including an antler chandelier that is no longer hanging, old black-and-white tile hidden beneath the current floor, and molding carved by his mother. He offers to send Eve old blueprints, which matters because the house’s records are incomplete. Eve also notices Thomas secretly taking what seem to be pills while pretending they are mints. Under the banister, Thomas shows Jenny a carved symbol made by his sister Alison and says Alison believed it protected against bad luck, adding another strange, intimate layer to the house’s history.

Upstairs, Thomas continues identifying former rooms and family uses for them, while Paige repeatedly corrects his language and the two boys reveal their hostility when Kai slaps Newton. In the study, Thomas is unsettled because a stained-glass window is not where he remembers it being. A more serious discovery follows when he finds evidence that a dumbwaiter once ran from the upstairs hall to the basement and has merely been covered over with wallpaper. He explains that it was used to send items upstairs, even to sick family members, and then pauses outside Alison’s old bedroom, unable to go in. Sensing his private emotion, Eve leaves the family to continue on their own.

Back downstairs, Eve works by the fireplace until Shylo becomes rigid and terrified while staring at the basement door. Eve’s own old fear of basements resurfaces, and for a moment the tension suggests something is wrong below. The cause turns out to be only an ant on the doorframe, which calms Shylo, but the scene leaves Eve shaken. When the family comes back down, Thomas asks to tour the basement because it was once used to measure the children’s heights on the doorframe, but Eve refuses by claiming it is unsafe and unlit. Thomas accepts the refusal and starts to privately ask whether Eve has noticed anything unusual in the house, but the question is cut off by a fight between the boys.

As the family prepares to leave, Thomas and Paige realize Jenny has disappeared. While they search, Eve worries about Charlie’s delayed return and notices a mysterious blue light deep in the woods that vanishes as suddenly as it appeared. Then she hears voices upstairs and finds the family gathered around the torn wallpaper in the hallway. The hidden dumbwaiter door is open, exposing the shaft down toward the basement. Thomas concludes that Jenny found a way in and has likely gotten into the basement after all, turning the family’s nostalgic visit into a more immediate and unsettling crisis.
