Undertone (2026): Overview

What Is Undertone About?

The film stars Nina Kiri as Evy, a woman who co-hosts a paranormal podcast with her friend Justin (Adam DiMarco), where she plays the sceptic to his believer. After moving back home to become the caregiver to her dying mother (Michèle Duquet), she and Justin begin receiving audio recordings from a young married couple experiencing deeply unsettling paranormal noises in their home.

As Evy listens deeper into the tapes, she realises the pregnant woman’s experiences are mirroring her own life in uncanny, terrifying ways. Each new recording edges her further toward fear and paranoia — and a fate she cannot escape.

What makes Undertone genuinely special is its bold structural choice: Evy and her mother are the only characters ever shown on screen. Every other character — including Justin and the mysterious couple — exists entirely as a voice. The film’s horror is conveyed entirely through its extraordinary sound design.

Why Critics Are Raving About It

This isn’t your standard jump-scare horror. Critics at Collider called it one of the few horror films that is even more horrifying to hear than to see, while Perri Nemiroff described it as “remarkably unsettling — the first movie to keep me up at night since Paranormal Activity.” World of Reel

The premise is brilliantly simple — a woman listening to recordings of someone else’s paranormal terror, slowly realising it’s also her own story — and Tuason executes it with extraordinary restraint and precision. The film was shot on a tight budget in Rexdale, Toronto, yet sounds and looks like a major studio production. It’s a genuine debut triumph.
