Rebecca, Willa Holland is a woman with a troubled past who has taken a job at a mortuary. After earning her one-year sober chip from Narcotics Anonymous, her boss, Paul Sparks Delver, calls her to work the night shift. Rebecca embalms a body and then burns it, quietly questioning why both steps are necessary as she begins to sense something is off. Soon, strange things creep into her world: a shadowy figure flickers at the edge of her vision and the line between reality and nightmare grows uncomfortably thin. She drifts between the quiet aisles of the mortuary and a string of unsettling visions that won’t leave her alone.
She returns home to a disruption she can’t quite explain. Her sponsor, Kelly appears at the door in a state of urgency, claiming Rebecca called and asked her to come over, yet Rebecca has no memory of making that request. This fracture in memory and control marks a turning point; Rebecca’s eyes take on a unnerving yellow glow, and fear gives way to violence as she attacks and kills Kelly with a corkscrew through the temple. The moment is harrowing, and the aftermath leaves Rebecca grappling with a truth she hasn’t earned: something in the mortuary has followed her home.
The caller on the other end of the line is Raymond Delver, Rebecca’s boss, Paul Sparks again, who insists that the mortuary is safer and who promises to explain everything later. As Rebecca trades worried words with him, Kelly’s figure seems to return—standing just outside the doorway for a heartbeat, then vanishing—as if the boundaries between life, death, and the supernatural are collapsing around her. Rebecca rushes back to the mortuary, where Raymond awaits and begins to outline what is happening and what she must do, all while her eyes pulse with that same yellow light. A brutal cycle resumes: she lashes out at Raymond, who narrowly escapes and bolts the doors, trapping her inside.
Alone inside the quiet rooms, Rebecca wanders in a haze and briefly encounters the memory of her deceased father, a presence that adds weight to her fear. Raymond steadies the moment by speaking through the phone again, directing her to cut the wrist of a body and burn it. Rebecca obeys, but the visions persist and intensify. She repeatedly hallucinates as Raymond’s guidance shifts—from a steady mentor to a chilling, almost manipulative voice that pushes her toward ever darker acts.
Seeking control, Rebecca uncovers tapes in the basement. In them, Raymond explains that a ritual is needed to stop the demons: they must be embalmed with a reagent and burned. The reagent, it is revealed, is the blood of a woman Raymond has locked in a box. With this forbidden knowledge, Rebecca confronts a new layer of danger and begins to perform the act he prescribes. She places a tablet bearing the demon’s name on a cadaver as the entity within begins to question her, and then she carries out the burning, attempting to sever the connection that has menaced her mind.
Morning finds Rebecca awake in the mortuary and driven to release the woman locked in the box. With bolt cutters in hand, she frees the woman, who immediately hurls accusations at Rebecca. Raymond reappears, revealing a tattoo on his chest that seems to enforce the woman’s fear. He explains that the woman isn’t merely dead—she died long ago—and that her blood is needed to prevent further deaths. He cautions Rebecca that she will never be free of the demons, but he offers a chance to learn to live above the fear.
As Rebecca steps outside, she allows herself a wary, uneasy smile at ordinary life in a nearby park. People go about their days, but a second glance reveals something else: a demonic figure watches from the brush, grinning at her. She looks back for a fleeting moment before returning to the mortuary, where the line between her fragile autonomy and the forces that haunt her remains perilously uncertain.
