UNDERTONE : Tuesday 14th April 2026.

I saw the M Rated 'UNDERTONE' earlier this week, and this Canadian horror film is Written and Directed by Ian Tuason in his feature film making debut. The film saw its Premiere screening at the Fantasia International Film Festival in late July last year, where it won the gold audience award for Canadian films. The film was released Stateside in mid-March, has generated largely positive critical reviews, cost US$500K to produce, and has so far grossed US$20M in Box Office receipts.

Evangeline 'Evy' Babic (Nina Kiri) is a young woman with a seemingly devout Catholic upbringing, living alone with her comatose mother (Michele Duquet), for whom she is the main caregiver. She and her friend Justin (voiced by Adam DiMarco) run 'The Undertone', a supernatural podcast where they report on such other worldly and paranormal occurrences, which Evy dismisses largely as fake while Justin is the believer. One day, Justin is sent an anonymous email containing a seemingly random string of letters and ten audio files, which they play on their podcast, and seek to gain some clarity. Justin is based in the UK, and so Evy dials into him at 3:00am in the mornings, given the time zone differences.

The files were recorded by a couple named Mike (voiced by Jeff Yung) and Jessa (voiced by Keana Lyn Bastidas), the latter of whom talks in her sleep, which Mike hopes to capture evidence of. In the first recording, Jessa sings 'London Bridge' in her sleep, which Justin then plays backwards and insists he can hear her saying 'Mike, kill all'. This leads Evy to research hidden messages in children's songs, and she becomes agitated when she discovers that playing 'Baa, Baa, Black Sheep', her favourite childhood song, in reverse reveals the message 'lick the blood off'. 

Evy later learns that she is six weeks pregnant. At her mother's bedside, Evy informs her of the pregnancy, but then admits that she feels unfit to be a mother. She later schedules an appointment at a local women's clinic. Playing additional recordings from Mike and Jessa reveal Jessa speaking what at first sounds like gibberish, but when played backwards reveals 'come in, Abyzou'. Through research, Evy and Justin learn that Abyzou is a demon in Mediterranean and European folklore who was said to cause miscarriages and drive mothers to murder their own children out of jealousy, as she herself was infertile. Evy notices increasingly strange occurrences around her, including her still-unconscious mother moving on her own, lights flickering around the house, the kitchen tap switching on of its own volition, and a small statue of the Virgin Mary that Evy placed in the closet out of the way reappearing in other parts of the house.

After recording the first eight audio tapes for their podcast they decide to make this a two parter and finalise the last segment by playing the final two audio recordings. In the final recording, Jessa insists she has to 'warn' someone who is 'listening', seemingly referring to Evy. Justin attempts to respond to the sender, only for the email to be automatically sent back to him as undeliverable. A caller claiming to be Mike and Jessa's neighbour reveals that the couple were found dead in their home at the foot of their staircase with plastic bags over their heads and crayon drawings of babies all over their walls. The autopsy revealed that Jessa was pregnant at her time of death. Another caller demands to speak to 'Mary' - the name Evy previously said she had always wanted to give her hypothetical child - and does not relent when Justin insists there is nobody there by that name. A final caller named Abby (voiced by Sarah Beaudin) begs for help in calming her incessantly crying child, ultimately murdering the infant despite Evy and Justin pleading with her not to. Evy then confesses that her mother has died, and that she killed her. 

Evy rushes upstairs, with the walls of the house now covered in black and red coloured crayon drawings of Abyzou and dead, bloodied infants. She rushes into her mothers bedroom where there is a neatly made up and empty bed, with the small statue of the Virgin Mary placed in the centre of the bed on the crisp clean sheets. She sees her mother standing in the bathroom, who turns and glides slowly towards her  seemingly attacking while screaming for her to stop.

Here first time feature Director Ian Tuason has crafted a modest little film that has Nina Kiri as the only walking and talking character on screen; an unassuming single suburban house location (which incidentally is the very house that Ian Tuason grew up in); weird camera angles and black screens to heighten the sense of dread; and an auditory experience that is sure to send shivers down the spine. With nods to that 2007 horror classic 'Paranormal Activity', the Director has here substituted the couple who set up a camera to document what is haunting them, for a recoding device set up by a couple to listen in on what is haunting them. The resulting sound design played back to the audience via this Podcast is top notch and is best heard in a theatre where the sound quality will far exceed anything you can get at home. However, all of that said, I left the theatre feeling just a little underwhelmed, as very little happens in between recording Evy's and Justin's Podcast episodes, and when the somewhat abrupt ending arrives it barely pays off. The film is devoid of jump scares or jolts to the system that make you sit bolt upright and pay attention, and despite the positives if does follow familiar genre types. I read somewhere that this could be the first instalment in a planned trilogy, and if so then the Director could be forgiven for that inconclusive ending, but if not . . . 

'Undertone' merits three claps of the Odeon Online clapperboard from a possible five claps.
