Secrets in the Walls

Molly, Lizzie, and their mother Rachel move from downtown Detroit to Ferndale, Michigan, into a house that feels immediately heavy with memory. The place is old, its floors creak, and shadows cling to the corners as if the house is listening. They hope a fresh start will wash away the past, not be swallowed by it.

As days pass, the floors groan, objects shift when no one is watching, and unseen taps sound at the windows. A sense grows that the house remembers more than it should, turning ordinary moments into unsettling hints. The family struggles to label these oddities as mere quirks of an old home.

Rachel digs into the home's history and learns Greta, a 17-year-old German girl from the 1950s, lived there with an abusive husband. Greta disappeared while living in the house and no one ever saw her again. The past begins to breathe through the walls, hinting at a haunting rooted in real tragedy.

While exploring Lizzie's room, the family uncovers a skeleton sealed inside the wall, its bonds of wood scratched and warped by time. The markers suggest Greta was locked away while she was still alive. The discovery weighs heavily on the family, changing how they see the house.

Greta uses a keepsake necklace to slip into Lizzie's body, beginning with a subtle hum beneath the surface. Molly quickly suspects something is wrong and realizes the girl in Lizzie's skin isn't her sister. The body swap infects daily routines with a sense of danger and deception.

Despite Greta's presence, Molly remains alert but is limited in what she can reveal. She watches Lizzie's behavior closely, trying to warn their mother without tipping Greta off. The family begins to sense a growing unease, even as the swap stays hidden.

Rachel's ally arrives to perform a cleansing to expel the haunting. The ritual proceeds, unaware that Lizzie's body is Greta's. Molly abruptly enters, interrupting the cleansing and revealing to Rachel and her ally that the body inhabiting Lizzie is Greta.

After the revelation, Rachel realizes she must pretend not to notice the body swap and lure Greta back into the house for a final confrontation. This decision shifts the dynamic, turning ordinary days into a calculated trap for Greta. Molly supports the plan, understanding what must be done to reclaim Lizzie's life.

The planned confrontation unfolds on the grand staircase, a charged stage where past and present collide. Greta's instinctive confusion about Lizzie's memories gives Rachel a crucial edge in the struggle. The battle leaves everyone exhausted as the family fights to separate two lives within one body.

In the heat of the fight, Lizzie reclaims her body, and a fragile moment of recognition passes between mother and daughter. Greta falters as Lizzie's memories intrude, creating a narrow window for Rachel to act. The tension peaks on the staircase as two lives contend for control.

The struggle erupts into a fall down the stairs, leaving Lizzie injured and the truth momentarily obscured. Muffled silence follows as the family processes what happened and what it means for Greta's hold. The event marks a turning point in how they confront the haunting.

As Lizzie regains consciousness, a literary memory surfaces: Elizabeth, the heroine who embodies resilience. That moment grounds them, reminding them that the life Greta longed for still belongs to the living. The line becomes a quiet, guiding symbol for their post-haunting resolve.

With the danger contained, Rachel leaves the house behind, Molly and Lizzie in tow. Before they go, they discover the previous seller is courting new buyers, forcing a moral choice: warn future occupants or stay silent. Greta's ghost lingers, watching from an upstairs window as the house seems ready for new life, implying the past isn't easily buried.
