Detailed Plot Summary
A Haunting Admission
The story opens in a grim, shadowy bedroom where a young girl stumbles upon her mother’s lifeless body after a fatal overdose. This childhood trauma fundamentally fractures young Rose, shaping her entire future.
Years later, Dr. Rose Cotter operates as a dedicated therapist in a bustling psychiatric ward. Her days are exhausted by manic patients and severe cases, a deliberate choice to outrun her own unresolved demons. She meets with a highly agitated patient named Carl, who frantically mutters about his imminent death before Rose manages to calm the situation.
The Infectious Grin
Rose is soon called to an emergency session with Laura Weaver, a distressed PhD student. Laura is utterly hysterical, claiming a malevolent entity stalks her. This unseen terror adopts the faces of both strangers and loved ones, flashing a sinister, unnatural grin.
Rose tries to ground Laura, diagnosing her with severe trauma-induced hallucinations after Laura witnessed her own professor brutally bludgeon himself. Laura violently rejects this medical explanation. She screams that she is about to die, convulsing in sheer terror.
When Rose desperately calls for help and turns back around, the atmosphere instantly freezes. Laura is suddenly calm, standing eerily still with a grotesque smile plastered across her face. Holding a jagged shard from a shattered vase, she slowly and deliberately slashes her own throat, leaving Rose drenched in blood and entirely paralyzed by shock.
Slipping Reality
Police detectives arrive to process the gruesome scene, including Joel, Rose’s former romantic partner. Despite explaining the tragedy to her superiors and authorities, the horrific image of Laura's smiling suicide deeply infects Rose's psyche.
She returns to the home she shares with her fiancé, Trevor, but peace is completely unattainable. A quiet dinner with her sister Holly and brother-in-law Greg erupts into a bitter argument. Rose's frayed nerves snap under the weight of Holly’s trivial complaints regarding a forgotten birthday present for her nephew.
Attempting to maintain her professional facade, Rose returns to the hospital. However, reality begins to bend. She glimpses Laura standing perfectly still in the dark corners of her vision. Even worse, she hallucinates her manic patient Carl sporting the exact same nightmarish smile, screaming that her death is rapidly approaching.
The Birthday Massacre
Ordered to take a mandatory leave of absence, Rose tries to normalize her life by attending her nephew Jackson’s birthday party. She wraps a toy train she meticulously selected for him.
The suburban backyard is filled with laughing children and relaxed parents. Jackson eagerly tears into Rose’s gift. The joyous atmosphere abruptly shatters into chaotic screaming. Inside the pristine box lies the bloody, mutilated corpse of Rose's missing pet cat, Mustache.
Rose stammers, desperately pleading her innocence while the horrified crowd backs away. In the commotion, she spots a party guest flashing that unmistakable, horrific smile. Panicking, Rose stumbles backward, crashing violently through a solid glass coffee table and shredding her arms.
Following the Bloody Trail
Trevor's patience evaporates, accusing Rose of inheriting her mother's severe mental illness. Isolated and terrified, Rose begins playing back the audio recordings of Laura’s fatal session. Hidden beneath the hysterical cries, she isolates a faint, guttural breathing noise that chills her to the bone.
Desperate for answers, she tracks down Victoria, the grieving widow of Laura’s professor. Victoria coldly reveals that her husband was entirely consumed by visions of a dark entity right after watching a woman named Anna Powell violently end her own life.
Recognizing the lethal pattern, Rose turns to Joel. Utilizing his police access, they uncover a terrifying chain of events. Security footage confirms that Anna Powell gouged her own eyes out merely days after watching a stranger impale himself at a gas station. Every single victim witnessed a smiling suicide, passing the invisible curse like a parasite.
The Sole Survivor
Joel’s deep dive into the police archives yields a singular anomaly. Amidst a chain of twenty suicides, one man managed to break the cycle. Robert Talley watched his business partner die, but he is currently alive, serving a sentence in a maximum-security prison.
Rose and Joel secure a tense visitation with the incarcerated man. Robert is a nervous wreck, whispering frantically about the entity. He explains that the parasite feeds purely on severe trauma. To survive, the host must brutally murder someone else in plain sight of a witness. The trauma of the murder forces the entity to latch onto the new witness, sparing the original host.
Horrified by the monstrous ultimatum, Rose refuses to become a murderer. As Robert realizes Rose is currently infected, he flies into a violent panic, screaming for the guards as he terrified the entity is in the room.
Nowhere to Hide
Rose's hallucinations escalate into a total sensory assault. The entity disguises itself as her therapist, Madeline, casually walking into Rose's living room before twisting into a grinning nightmare. Driven to the brink, Rose impulsively grabs a massive kitchen knife and drives to the hospital.
She envisions herself violently stabbing her patient Carl in front of her boss, Dr. Desai, intending to pass the curse. However, this brutal execution is yet another hallucination. Rose wakes up in her car with the real Dr. Desai staring at the weapon in her hands. She speeds off into the night, officially a wanted woman.
Realizing that the entity requires a witness to survive, Rose formulates a desperate, sacrificial plan. She drives out to the remote, rotting ruins of her childhood home, cutting herself off from the rest of humanity.
The Final Confrontation
In the pitch-black decay of the abandoned house, the entity finally manifests. It takes the looming, monstrous form of Rose's dead mother. The psychological torture reaches its zenith as the creature forces Rose to admit the agonizing truth: she didn't just find her mother's body. She found her mother dying, heard her pleas for help, and chose to walk away.
The entity aggressively attacks, physically overpowering the exhausted therapist. In a final act of defiance, Rose grabs an oil lantern and smashes it. She sets the towering monster ablaze, watching it burn as the flames consume the cursed house.
Rose escapes into the cool night air, driving straight to Joel's apartment. She tearfully apologizes for her past mistakes, finally feeling the crushing weight of the curse lift. Joel offers a warm, comforting smile. Slowly, that smile stretches past the physical limits of a human face.
Movie Ending Explained
The final act pulls the rug out from under the audience with devastating precision. Rose's apparent victory over the entity and her escape to Joel's apartment is entirely fabricated by the parasite. She never actually left her rotting childhood home. The creature merely created a hyper-realistic hallucination to finally break her spirit and strip away her last shred of hope.
When the real Joel arrives at the abandoned property, tracking her phone, the tragic inevitability of the curse is sealed. The entity sheds its human disguises, revealing its true form: a towering, skinless monstrosity with nesting, smiling jaws. It forces itself directly into Rose's mouth, completely taking over her body. As Joel breaks down the door, he becomes the mandatory witness. Rose turns to him, flashes the sinister grin, and sets herself on fire, permanently trapping Joel in the devastating cycle of trauma.

The central entity acts as a literal manifestation of grief, illustrating how unchecked trauma acts like a contagion that ultimately destroys everything it touches.

This highly experimental cinematic triumph practically crawls under the viewer's skin. Tracks like "Trauma Loop" heavily utilize human breath and sharp, jagged noises that perfectly mirror the protagonist's spiraling mental degradation.

Behind the Scenes Insights
- Director Parker Finn initially crafted the concept in his highly successful 2020 short film, "Laura Hasn't Slept".
- Caitlin Stasey, who played the doomed patient Laura, was the actual star of the original short film that inspired this feature.
- The horrific, unnerving smiles seen throughout the runtime were achieved entirely through practical acting, without any digital manipulation.
- The massive entity at the climax was an incredibly complex, 9-foot-tall animatronic puppet operated by multiple technicians.
- Sosie Bacon isolated herself on set to properly channel the crushing loneliness and paranoia of her doomed character arc.
- The film was originally slated for a strictly streaming release on Paramount+, but spectacular test screenings pushed the studio to grant it a full theatrical run.
- The sound design team recorded actual animal distress calls and heavily pitch-shifted them to create the monster's unearthly shrieks.
- Cinematographer Charlie Sarroff deliberately used wide, imposing lenses to make the backgrounds feel unusually vast and deeply threatening.
Inspirations and References
- The mechanics of passing a fatal curse through physical witnessing draws heavy thematic inspiration from Hideo Nakata's "Ringu" (The Ring).
- The concept of an inescapable, shape-shifting entity slowly walking toward its victim mirrors the dread-inducing formula of David Robert Mitchell's "It Follows".
- The psychological ambiguity—blurring the line between supernatural haunting and severe mental breakdown—echoes Roman Polanski's "Rosemary's Baby".
Alternate Endings and Deleted Scenes
While the brutally bleak ending was always Parker Finn's definitive vision, the director admitted to shooting several minor variations of the final confrontation. Some cuts slightly extended Rose's fiery hallucination, giving a brief, false sense of victory before ripping it away.
A few minor conversational scenes between Rose and Trevor were trimmed to maintain the aggressive, suffocating pace of the second act. Ultimately, no "happy ending" was ever filmed, as the narrative explicitly demands the grim continuation of the trauma cycle.
Book Adaptations and Differences
This feature is not based on a novel or comic book. It is a direct, expanded adaptation of Parker Finn's own award-winning horror short, "Laura Hasn't Slept," taking the core premise of a sleep-deprived, terrified woman and expanding it into a massive, world-building lore regarding trauma-based viral curses.
