THE UNDERTONE is a new horror movie getting its World Premiere at Fantasia 2025. Based on the plot, I wasn’t sure what to expect of it, but I was definitely pleased with what I got. Or rather, I was on the edge of my seat and often horrified.

The plot is about a true crime podcaster caring for her dying mother, but the main plot turns more towards the paranormal. We’re in the one house from start to finish, and it’s entirely possible our main character is losing her mind. But then again, we might be too.

With The Undertone, we meet Evy (Nina Kiri) as she has moved in with her mother to care for her in the final days of her life. Instead of a hospice, she wants to be in her own home, so Evy is there to care for her. However, her mom is no longer conscious, so the days are long.

In that sense, it’s good that Evy has a job that she can take on from any location. She’s a podcaster, and with a remote partner, Justin, they’re working on the next episode. It’s a podcast about true crime, but usually with a paranormal or supernatural twist.

The podcast is called “The Undertone”, and while Evy is the skeptic, non-believer, her co-host Justin (voiced by Kris Holden-Ried) wants to believe. While on this solitary deathwatch, Evy tries to focus on their next podcast, but it’s a very odd one that seems to awaken something in her.

Justin has received an email with mysterious audio files. There are ten in total, and as they listen to them, something very strange seems to unfold for the two people in the recordings.

The recordings are of Mike and Jessa, who experience something extraordinary at night and have recorded it. What happens in these recordings will involve superstition, hidden messages in children’s songs, religion, and lots of sinister connotations.
