The Undertone is a 2025 Canadian horror film written and directed by Ian Tuason, in his directorial debut.[1] The film stars Nina Kiri as Evy, a woman who hosts a paranormal podcast with her friend Justin (Kris Holden-Ried), where she is the skeptic to his believer; after moving back home to become caregiver to her dying mother (Michèle Duquet), she is sent recordings of a married couple experiencing paranormal noises in their home, drawing Evy into fear and paranoia.[2]

Evy is the only character to be shown on-screen in the film. All other characters are heard only as off-screen voices, thus conveying the film's horror through its sound design.[2]
