The film, Undertone, first gained major momentum at the Fantasia International Film Festival in July 2025. It secured the Gold Audience Award for Best Canadian Feature. Horror enthusiasts can finally experience this auditory nightmare when it arrives in select theaters and on digital platforms later this year.

The casting and character dynamics provide a deep emotional core to this unsettling auditory mystery.

The premise centers on Evy, a skeptic co-hosting a spooky podcast while simultaneously caring for her dying mother.

Nina Kiri, known for her work in The Handmaid's Tale, leads the cast alongside Adam DiMarco and Michèle Duquet. The production also features Keana Lyn Bastidas and Jeff Yung under the direction of Ian Tuason. Producers Dan Slater and Cody Calahan have collaborated to bring this setup to the big screen.

Evy must confront the possibility that the sounds she analyzes for entertainment are actually targeting her. This tension between logic and fear serves as the driving force behind the most chilling sequences in the movie.
