Iris Blum, a former horror author grappling with dementia, resides in a secluded home in Braintree, Massachusetts. This eerie residence was constructed by a man for his new bride, but on their wedding day, both the bride and groom mysteriously vanished, leaving the house tragically unfurnished. To provide care for Iris, her estate manager, Mr. Waxcap, hires live-in nurse Lily Saylor.
On her very first night at the estate, Lily experiences an unsettling encounter when an unseen force violently wrenches the telephone from her hand, and she catches a glimpse of a figure dressed in white, walking backward. As time passes, a disturbing spot of black mold appears on the wall, growing ever larger, while Lily also notices that a corner of the rug at the base of the staircase has been mysteriously flipped up—curiously, she is the only one traversing the first floor.
Throughout her time with Iris, the former writer refers to Lily as “Polly,” a name that Mr. Waxcap explains belonged to the main character in Iris’s most renowned novel, The Lady in the Walls. When Lily delves into a copy of the novel, she uncovers unsettling implications—that Iris had a connection to Polly and may be recounting a forgotten tale from her own past. The story takes us back to 1812, where Polly, clad in a wedding dress and blindfolded, wanders through the abandoned house, unaware of the sinister events unfolding above her.
In a chilling episode within the kitchen, Lily hallucinates that her arms are now grotesquely bloated and speckled with black mold. Later that evening, she spots a reflection of the white-clad figure but is met with empty air when she turns around. Her curiosity drives her to explore a hidden cardboard box in a closet, where she discovers rough drafts for The Lady in the Walls. This revelation prompts her to suspect that the narrative may not just be fictional, but rather an ominous recounting of a murder that transpired in the home.
As the scenes shift back to 1812, blindfolded Polly, relying on her sense of touch, stumbles upon a wall stripped of wood—remarkably, the same area now tainted with mold in the present day. When Polly dares to lift her blindfold, she locks eyes with her husband, feeling a sense of dread as her husband suddenly strikes her down with a hammer, concealing her lifeless body behind the wall.
In the present, Lily attempts to engage Iris in conversation about the book, only to be met with fury as Iris accuses Polly of betrayal and abandonment, reminding her that even the most beautiful things succumb to decay. A chilling encounter unfolds as Polly’s ghost appears to Iris, whispering dark secrets. In her desperate quest for understanding, Lily discovers the wall boards have been removed and heaped next to the mold-infested wall, only to confront the apparition of Polly, leading to her sudden demise from a heart attack.
Days later, Mr. Waxcap stumbles upon the grim scene, uncovering both Lily’s and Iris’s lifeless forms. Years roll by, and a new family moves into the haunted house, now under the watchful eyes of Lily’s ghost, forever intertwined with the tragic history of the place.

Unravel the ending of I Am the Pretty Thing That Lives in the House (2016) with our detailed explanation. Understand the final scenes, character fates, and unresolved questions.
In the haunting film I Am the Pretty Thing That Lives in the House, the ending leaves viewers with a sense of ambiguity and unresolved mystery. Throughout the story, Lily, the nurse, is haunted by the presence of a ghost believed to be Polly, a character from the house’s haunted past. Polly was supposedly a real woman who lived in the house in 1813 and was murdered by her husband, her body sealed in the walls, according to the legend. As the story unfolds, Lily begins to hallucinate and see signs of Polly’s presence—such as mold growing where Polly was buried—and Iris, the novelist she cares for, repeatedly calls Lily “Polly,” blurring the line between reality and hallucination.
In the movie’s final moments, Polly’s ghost whispers something inaudible into Iris’s ear, further deepening the mystery. Lily, overwhelmed by these supernatural encounters, eventually dies of a heart attack after witnessing what she believes is Polly in her full ghostly form. Iris also dies soon after, leaving the house behind. The narrative suggests that Lily may become part of the house’s spectral history—perhaps she is now a ghost herself, forever lingering there. The film’s ambiguity invites viewers to interpret what was real—whether Polly was a genuine ghost, a manifestation of Iris’s dementia, or a figment of Lily’s imagination—and whether the house itself is cursed to trap spirits or memories from the past. Ultimately, the ending emphasizes that much remains unresolved, making the story more about atmosphere and mood than concrete answers. The eerie atmosphere and open-ended conclusion leave audiences pondering the true nature of the hauntings and the film’s characters, making it a haunting meditation on memory, death, and the unknowable past.
Discover the spoiler-free summary of I Am the Pretty Thing That Lives in the House (2016). Get a concise overview without any spoilers.
In the damp, shadow‑laden corridors of a sprawling Victorian mansion, a new caretaker arrives to tend to the needs of a once‑famous horror writer. Lily Saylor, a diligent nurse accustomed to quiet routines, steps into a world where the house itself seems to breathe, its aged timber whispering stories of the past. The author, Iris Blum, lives in near‑solitary confinement, her memories drifting like the dust that settles on every surface, while the estate’s manager, Mr. Waxcap, oversees the fragile arrangement that keeps the household functioning.
From the moment Lily sets foot on the creaking floorboards, the ambience of the residence exerts an almost tangible pressure. Faint drafts move curtains without cause, distant footsteps echo when no one is near, and the very walls appear to pulse with an unseen presence. The relationship between nurse and author unfolds with a delicate mixture of professional care and quiet curiosity, as Lily seeks to understand the reclusive writer’s habits while feeling increasingly drawn into the house’s lingering melancholy.
The film’s tone is deliberately slow‑burning, allowing the audience to linger on the melancholy beauty of dimly lit rooms, the soft rustle of turning pages, and the subtle, unsettling shifts in the environment. Though no overt threats appear, an undercurrent of dread suggests that the mansion holds secrets older than the living occupants. Iris’s enigmatic past and her own ghostly stories hint at a connection between the house’s decay and the mysteries that have long haunted its occupants.
Against this backdrop of fading grandeur and quiet terror, the story invites viewers to wonder whether the true horror lies in the lingering memories of a troubled life, the palpable weight of the house itself, or the invisible forces that seem to watch from its shadowed corners.
