Undertone Trailer Breakdown: Nina Kiri Leads A24’s Next Psychological Nightmare
A24 is back with another chilling descent into the unknown, and this time it’s coming through your headphones. The official trailer for Undertone has dropped, and it puts Nina Kiri front and center in what looks like a tense, spiraling psychological horror story built around podcasts, paranormal tapes, and generational trauma.
Set for a US release on March 13, 2026, Undertone stars Nina Kiri as a podcast host who specializes in spooky content. She relocates to care for her dying mother, but what should be a heartbreaking, grounded life transition quickly twists into a nightmare when she begins receiving eerie audio recordings from a pregnant couple plagued by unsettling, possibly supernatural encounters. As she digs deeper into their story, she realizes their experiences start to mirror her own, blurring the line between her work, her memories, and her sanity.
A Horror Film Built For The Podcast Era
One of the most intriguing elements teased in the trailer is how Undertone uses the language of modern true-crime and paranormal podcasts to tell its story. Instead of the typical haunted house or cursed object setup, the horror here seems to creep in through audio—distorted voices, unsettling background noise, and the sense that something is hiding just out of frame, or just beneath the sound.
This approach makes Undertone feel tailor-made for fans of narrative podcasts and found-footage stories. The recordings sent to Nina Kiri’s character aren’t just plot devices; they appear to be the core of the film’s tension. Each new tape escalates the dread, pushing her closer to a mental breaking point as she becomes consumed with the couple’s haunting experiences.
Parallels, Trauma, And A Descent Into Madness
The heart of the movie looks to be the unsettling connection between Nina’s character and the mysterious couple on the recordings. The synopsis hints that their story parallels hers, suggesting that Undertone isn’t just about ghosts or demons, but about the echoes of unresolved trauma and generational pain.
The trailer teases moments of blurred reality: flickers of something in the corner of the frame, disorienting sound design, and a sense that the boundaries between the tapes and Nina’s real life are dissolving. As each recording plays, it doesn’t just inform her podcast—it infects her thoughts, her home, and her fragile emotional state as she tends to her dying mother.
Expect unreliable narration, psychological breakdowns, and plenty of “Did that really happen?” moments. Undertone seems designed to keep audiences second-guessing every scene.
A Cast And Creative Team Ready To Disturb
Nina Kiri leads the film with the kind of intense, haunted presence that psychological horror thrives on. She’s joined by Adam DiMarco, Jeff Yung, Keana Lyn, Kris Holden-Ried, and Michèle Duquet, rounding out a cast that suggests a grounded, character-driven story rather than a jump-scare-heavy spectacle.
Director Ian Tuason appears to be leaning hard into mood and atmosphere. From the trailer alone, the film’s visual palette is cold and intimate, with dark interiors, flickering lights, and close-up shots that keep you trapped in the characters’ emotional turmoil. The sound design is clearly a major focus as well—every static burst, echo, and muffled noise feels like a clue or a threat.
Why Undertone Should Be On Your Horror Radar
If you’re a fan of:
– A24’s slow-burn psychological horror
– Podcast-centric stories like Archive 81 or narrative true-crime series
– Films that use sound as a primary source of fear
– Narratives about family, grief, and inherited trauma
then Undertone should be high on your must-watch list for 2026.
The trailer promises:
– A tense, audio-driven mystery centered on eerie recordings
– An emotionally charged story about a woman caring for her dying mother
– A chilling overlap between fiction, documentation, and personal reality
– A carefully constructed spiral into paranoia and madness
It’s the kind of horror that doesn’t just make you jump—it lingers, gnawing at you long after the screen goes dark.
