We Used to Live Here

On a snowy Friday night, Eve Palmer answers the door of the remote fixer-upper she shares with Charlie Bastion and finds a family of five asking to come in. The father, Thomas Faust, says he grew up in the house and wants to give his children a brief tour. Eve is immediately frightened but too conflict-averse to refuse cleanly. After first turning them away and then feeling guilty, she invites Thomas, his wife Paige, and their children Jenny, Kai, and Newton inside.

Once the tour begins, Thomas proves he knows the house intimately. He recalls vanished fixtures, hidden original tile, and family details carved into the woodwork. He shows Jenny a protective symbol once carved by his supposed sister, Alison. Eve, who already feels unsettled by the house's incomplete records and odd layout, becomes more disturbed when Thomas notices a covered-over dumbwaiter and starts to ask whether she has ever noticed anything unusual there. Before he can finish, Jenny disappears. Thomas and Eve search the basement, where Eve finds strange rooms, a trail of ants, and Thomas behaving in an unnervingly blank, motionless way. Jenny is eventually confirmed to be hiding in a concealed concrete nook, but Thomas insists she will only come out if left alone.

Charlie arrives and briefly steadies Eve, but dinner with the Fausts only makes the family feel more threatening. Paige is openly judgmental about Eve and Charlie's relationship, Thomas remains oddly detached, and the children reveal a tense household dynamic. Jenny eventually emerges filthy from the basement, and the Fausts attempt to leave, only for the storm and the closure of Kettle Creek Bridge to strand them on the mountain. Charlie lets them stay in the upstairs study. That night Thomas sleepwalks into the snow, weeping and asking for Alison. Back inside, he tells Eve and Charlie that Alison became convinced the house and even the people in it were changing around her, while his religious parents treated her fear as demonic rather than medical. Charlie interprets the story as psychosis made worse by abuse, but Eve is left even more alarmed.

Before dawn, Eve finds the basement door open. Using the same knock pattern Thomas used on Jenny, she gets an answering knock and sees what looks at first like a crouching child on the stairs. The figure then rises into a tall, gaunt adult. Terrified, Eve wakes Charlie, but Charlie refuses to investigate until morning. When Eve wakes later, Charlie is gone, Thomas is cooking breakfast in Eve's kitchen, and the family is acting as if they belong there. Thomas says Charlie left for town and that the basement is clear. Eve cannot find her phone, cannot borrow one because the family claims to be on a church-mandated digital fast, and becomes more frightened when she discovers Charlie's locket rehung over the fireplace.

Eve leaves with Shylo, her dog, to find help from a neighbor named Heather. Charlie does answer the phone from Heather's house, but the call is confusing and abrupt rather than reassuring. Heather then reveals crucial information: the local records were stolen, not lost in a fire, Thomas was an only child, and Alison was not his sister at all but a mysterious girl found on the property and taken in by the Fausts. Heather says Alison became convinced the house and its occupants were changing and eventually stabbed young Thomas dozens of times with a fountain pen before being taken away. The visit becomes even stranger when Eve notices a toy monkey resembling Mo, a lost object from her childhood, and hears unexplained movement in Heather's house. On her way back, Eve follows tracks into the woods, discovers a hidden cabin marked OLD HOUSE, and finds walls covered with maps and notes about strange places. A scarred old man inside panics at her presence but warns that the family in her house is not what they appear to be.

When Eve returns home, Thomas still has not left. Determined to force the family out, she climbs into the attic for tire chains. There she finds Charlie's discarded camera, sees Thomas outside in a violent private outburst, and notices a carved warning telling her not to forget which house she is in. Then the dumbwaiter rises on its own. Wet adult footprints lead through the attic, and a tall woman in a torn hospital gown advances toward Eve out of the dark. Eve falls through the attic hatch and is injured. Afterward, Thomas and Paige doubt her account, and when Eve later confronts Kai over a phone she believes is hers, Shylo bites him during the struggle. The Fausts finally leave. Yet the house immediately seems wrong again: a stained-glass window has changed into plain glass, false whimpers lure Eve toward the basement, and she decides she and Shylo must flee.

Eve reunites with Charlie near the driveway, but Thomas has already had time to frame Eve as unstable. Charlie agrees to leave only after confirming the impossible window change for herself. They drive to a motel, where Charlie calms Eve by accurately recalling the story of how they met. Then, in the middle of the night, Eve answers Charlie's phone and hears another Charlie on the line, terrified and claiming the real Charlie never left the house. The caller warns that the woman in the motel room is an impostor and that even the dog with Eve is not the real Shylo. When Eve realizes the woman beside her lacks Charlie's finger tattoo, she runs, steals the truck, and drives back toward the mountain despite police attention and a frightening encounter with a strange girl on the road.

Back at the house, Eve finds it reset into something staged and hostile. The table is laid for six, the exits are sealed, and a hospital-gowned woman armed with a hammer forces her into a deadly game of hide-and-seek. In a hidden room beneath the basement, Eve discovers paintings and photographs that contradict Thomas's story. A note from Alison says Thomas is not her brother, has been in the house since before it was built, rewrites memory, and replaces real people with mimics. Alison warns that directly resisting the false story only strengthens his control; the only chance is to play along until he becomes afraid or angry enough to slip.

Following a trail of ants, Eve enters an impossible labyrinth beneath the house and finds Mo, her lost childhood monkey, along the way. She also finds a grotesque, seemingly ancient version of Charlie, who briefly wakes and warns her to hide before the hospital-gowned woman arrives. When Eve hides in a wardrobe, Alison shares her memories directly with her: Thomas came out of the woods into Alison's childhood home, gradually displaced her place in the family, twisted her parents into religious abusers, and drove Alison to stab him in desperation before she was institutionalized as delusional. Later, Thomas appears younger in a brightly lit, partially renovated version of the basement, as if time itself has shifted. After he leaves, Eve takes the hammer and heads upstairs.

The house has transformed again into a mid-century domestic scene. Thomas catches Eve and insists she is not Eve Palmer but his unstable sister Emma, recently released from psychiatric care and now living with his family as a last chance. Remembering Alison's warning, Eve pretends to comply. At dinner, the entire family treats her as Emma. The charade collapses when Paige appears wearing Charlie's locket. Eve seizes Paige with a corkscrew and demands to know where Charlie is. In the ensuing struggle Paige stabs Eve in the leg, but the corkscrew ends up lodged in Paige's throat and she dies. Thomas attacks Eve in grief and rage. She wounds him horribly with a hammer and then with tire chains, briefly hearing him drop the Emma story and call her Eve, but she still cannot escape the locked house or find Charlie. Police arrive, overpower her, and remove her while Thomas's version of the scene hardens around them.

Nearly three years later, Eve is confined in Greenwood Asylum under the name Emma Faust after the case becomes known as the Faust Family Bloodbath. Records say Thomas owned the house, neighbors support his history, and even Charlie now exists as Charlotte, remembering a life in which Emma left her rather than one in which Eve and Charlie lived together. Eve learns to act improved for Dr. Preston Karver while privately clinging to her own memories. Then Thomas visits, claiming he forgives her. Before he leaves, he gives her Charlie's brass locket. Inside is a photograph of Eve Palmer, the one piece of concrete evidence that her erased life was real.
