What does the Undertone trailer reveal about the movie?
The just-released Undertone trailer introduces audiences to a chilling horror concept where sound itself becomes the source of terror. The teaser leans heavily into unsettling audio design — eerie whispers, distorted noises, and ghostly recordings play over sparse visuals, creating an atmosphere that’s uncanny and deeply unsettling.
What is Undertone about?
Undertone centers on Evy, a paranormal podcast host whose life begins to unravel when she receives a series of mysterious audio files — recordings that seem to unleash something sinister. As she listens, the boundary between eerie sounds and real danger collapses, hinting at a haunting journey where silence may be more terrifying than noise.
The film stands out for its minimal visual storytelling, with Evy often the only character shown on-screen while others exist through voice recordings and disembodied sounds, giving the movie a unique sensory horror experience.
