Eve and Charlie have recently moved into an isolated Victorian house in the Pacific Northwest when Thomas Faust arrives claiming he grew up there and leads his family on a tour. After a storm traps the family overnight, strange events accumulate—Thomas sleepwalks outside crying, Jenny hides in the basement, and Eve encounters a growing ghostly figure in the night. The next morning Charlie is gone and her locket hangs over the fireplace, sending Eve on a desperate search for help and answers from a neighbor named Heather. An old man in a hidden forest cabin confirms her fears, and a ghost in the attic leaves Eve injured and more determined to flee. Eve convinces Charlie to leave for a motel but doubles back to Old House alone, where she discovers photos proving Thomas replaced Alison in her own life and survives a violent climax before being arrested. Thomas's final visit to deliver Charlie's locket to Eve in the psychiatric hospital confirms her former life was real and that she remains trapped in an alternate timeline.

From the moment Thomas arrives with dirt on his jacket and no car in sight, small details signal that something is deeply wrong with the Faust family. Dinner is filled with tension—Paige's faded circle tattoo, an unexpected prayer, and Thomas's partial truths about his past paint a picture of a family performing normalcy rather than living it. Charlie's gift of a locket and Thomas's account of his parents blaming demons for his nightmares add emotional texture to a night that grows increasingly strange. As Eve searches for help the next morning, the neighbor's address has changed, a chimp toy in Heather's home mirrors Eve's lost childhood toy Mo, and footprints in the forest lead nowhere. Back in the house, a warning message on the windowsill and Thomas's bizarre self-harm in the yard hint that forces beyond his control are at work, while a scuffle over a phone leaves Eve doubting her own grip on reality.

Subtle signals accumulate—Shylo's fixation on the basement door, Thomas's visible discomfort when Charlie mentions demolishing the house, and Shylo's uncharacteristic trust of the stranger Heather. Heather's revelations that the library records were stolen and that Alison was not Thomas's sister but a foster child who wandered from the woods begin to reframe Thomas's entire fabricated past. A cabin filled with supernatural blueprints, a box labeled Charlotte's Stuff, and Thomas's lie about the attic all tighten the evidence against him. At the motel, a phone call from what seems to be the real Charlie forces Eve to abandon safety and return to Old House, where she relives Alison's memories inside a wardrobe and fully understands that Thomas is an ancient entity who replaces people's realities. By the time police interrogate Eve and confirm that no record of her former life exists, the full weight of her permanent entrapment in a different timeline becomes inescapable.
