The first thing you notice about undertone is how quiet it is; not just in its audio mix, but in how it’s shot — primarily steady wide shots that slowly pan across empty rooms, allowing your eyes to frantically scan for something amiss. It’s an understated form of filmmaking that allows for the movie’s scares to hit all that much harder. And when those scares do come, they’ll linger with you for an astonishingly long time.
The film follows Evy (Nina Kiri), the resident skeptic on a paranormal podcast that she co-hosts with her old friend Justin (Adam DiMarco). Justin, the believer, receives a strange series of audio files sent by an anonymous email and shares them with Evy live on the podcast. The recordings appear to be of a couple, Jessa (Keana Lyn Bastidas) and Mike (Jeff Yung), who start recording themselves at night after Jessa starts speaking mysteriously in her sleep. But as the recordings continue, the sounds they catch become more sinister and appear to start influencing Evy’s life in more and more threatening ways.
