| undertone Ending Explained: Podcast Horror Film Leaves Viewers With Unsettling Questions. (Credits: IMDb) |
The 2026 horror film undertone closes on an eerie note that has left viewers debating what exactly happened to its central character. Written and directed by Ian Tuason in his debut feature, the Canadian film strips horror down to its bare elements, building dread almost entirely through sound, silence and the fragile mental state of one woman drawn into a mystery she cannot control.
At the centre of the story is Evy, played by Nina Kiri, a paranormal podcast host who prides herself on being the sceptic of the duo. Her co-host Justin (Adam DiMarco) is the believer, always ready to chase the next supernatural lead. Their show, The Undertone Podcast, explores strange recordings and urban legends, but what begins as another curious case soon drags Evy into a spiral of fear.
The film unfolds almost entirely inside a quiet house where Evy has returned to care for her dying mother, Mama (Michèle Duquet). With the house filled with religious imagery and the heavy presence of approaching loss, Evy’s life is already emotionally strained before the mystery recordings arrive.
Justin receives ten audio files sent anonymously. They appear to document a married couple — Mike (Jeff Yung) and Jessa (Keana Lyn Bastidas) — whose home has been plagued by disturbing sounds during the night. At first the recordings resemble typical paranormal podcast material: whispers, sleep-talking, and eerie background noises.
But as Evy and Justin continue analysing the files, the situation becomes more disturbing. Jessa’s sleep-talking begins to sound like something far darker, at times resembling distorted nursery rhymes and strange phrases spoken in reverse. The recordings hint at something lurking beneath the ordinary sounds of the home.
While investigating the files, Evy’s personal life begins to unravel. She is struggling with exhaustion while caring for her bedridden mother. Her relationship with her absent boyfriend is falling apart. She also discovers she is pregnant, raising questions about what direction her life will take.
These personal pressures blur with the supernatural mystery. Evy’s scepticism starts to crumble as the recordings grow more unsettling. The nursery rhymes mentioned in the audio clips link to disturbing stories involving children, while strange sounds begin appearing in Evy’s own house.
The deeper Evy goes into the recordings, the more the boundaries between the audio files and her own reality seem to collapse.
The film opens with Evy preparing another episode of her podcast from the dining room of her mother’s house. Her mother lies unconscious upstairs, leaving Evy to manage both caregiving and the show.
Justin introduces the mysterious recordings during one recording session. He suggests that they listen to the files together while documenting their reactions for the podcast. Evy initially treats it as another case to debunk.
The early recordings capture Mike describing how his wife has begun talking in her sleep. Jessa denies any memory of it, prompting Mike to record the nights as proof.
As Evy and Justin analyse the clips, they slow down the audio, reverse certain lines, and isolate background noises. The process reveals fragments of unsettling phrases and eerie melodies hidden within the recordings.
Meanwhile, Evy’s home life grows increasingly tense. Her mother’s condition deteriorates. The quiet house feels heavier each night, and Evy struggles with sleeplessness and anxiety.
The film’s tension builds as Evy continues listening to the files despite growing warnings — both from Justin and from her own instincts — that something about them is deeply wrong.
By the time the pair reach the later recordings, the situation captured in Mike and Jessa’s home appears to have escalated dramatically. Strange voices, distorted cries and violent disturbances begin appearing in the audio.
At the same time, Evy begins hearing unexplained sounds inside her own home.
The final act arrives when Evy decides to play the tenth and final recording.
The ending of undertone deliberately avoids clear answers, but several clues throughout the film suggest what may be happening.
When Evy listens to the final recording, the soundscape becomes overwhelming. The audio erupts into layers of whispers, reversed speech and distorted noises. It feels less like a recording and more like an intrusion.
At the same time, Evy’s house begins responding to the sound. Doors creak, objects shift and shadows move through the empty hallways behind her.
The implication is that the recordings are not merely documentation of paranormal activity. They may act as a channel, allowing whatever presence exists within them to spread beyond the original location.
Throughout the film, Evy repeatedly pushes forward despite warnings. She insists on finishing the recordings, driven by curiosity and the need to uncover the truth.
By playing the final file, she effectively completes the sequence — possibly triggering whatever force the recordings carried.
Another interpretation links the events to Evy’s emotional state. The film surrounds her with themes of life, death, belief and uncertainty: her dying mother upstairs, her unexpected pregnancy, and her scepticism about faith.
The recordings mirror these tensions. Nursery rhymes about children, religious imagery in the house, and whispers about unseen forces all weave together.
Rather than presenting a clear supernatural explanation, the film suggests that Evy has entered a psychological and spiritual collapse where sound itself becomes threatening.
The final moments leave her trapped in a storm of noise and darkness, with no confirmation of what survives the experience.
It is not a clean resolution — and that appears to be intentional. The film treats horror not as a puzzle to solve but as an atmosphere to experience.
As a debut feature, Ian Tuason shows remarkable control over mood. The film relies less on traditional horror tricks and more on silence, sound distortion and empty space.
By focusing on a single location and a single visible character, undertone becomes deeply claustrophobic. The audience experiences the events almost entirely from Evy’s perspective.
However, the story can feel slow in its middle section. Several plot threads — particularly Evy’s relationships and personal struggles — remain underdeveloped.
Where the film truly succeeds is its final stretch. The last fifteen minutes unleash a chaotic audio nightmare that turns the entire house into a sonic maze.
It is a bold approach that will divide audiences. Some viewers may find the ambiguity frustrating, while others will appreciate the refusal to over-explain.

Nina Kiri as Evy delivers a grounded performance that anchors the entire film. As the only character constantly visible on screen, she carries the emotional weight of the story.
Adam DiMarco as Justin appears only through voice during podcast sessions, representing the believer pushing Evy deeper into the mystery.
Michèle Duquet as Mama remains mostly silent yet crucial to the film’s emotional backdrop, symbolising the looming presence of loss.
Other voices heard through recordings include Keana Lyn Bastidas as Jessa, Jeff Yung as Mike, Sarah Beaudin as Abby, and Brian Quintero as Dr. Ram.
Despite limited screen presence, their audio performances drive the central mystery.
Is undertone based on a true story?
No. The film draws inspiration from internet horror culture, paranormal podcasts and modern urban legends, but the story itself is fictional.
Is the ending happy or sad?
The ending leans heavily toward unsettling rather than hopeful. Evy’s fate remains unclear, leaving viewers with a lingering sense of dread.
Why are most characters heard but not seen?
The film deliberately focuses on sound as its main storytelling device. By keeping characters off screen, the mystery unfolds primarily through audio recordings.
Will there be an undertone sequel or part two?
There is no official confirmation of a sequel. However, rumours about a possible continuation have circulated among fans.
If a follow-up ever materialises, it could explore the origins of the recordings or the entity behind them. Another possibility is a new set of characters encountering the same audio files, suggesting that the recordings themselves are the real threat.
Some industry chatter suggests the story might eventually expand, although nothing has been formally announced. For now, the idea of a sequel remains speculation.
With undertone, director Ian Tuason delivers a horror film that prioritises atmosphere over explanation. Its unsettling sound design and stripped-down storytelling may divide audiences, but the film undeniably leaves an impression long after the final scene fades out.
If you have watched undertone, what did you think really happened to Evy — supernatural forces, psychological collapse, or something else entirely?
