Undertone

Overview

A sound recordist living alone starts picking up eerie noises from beneath their home—low hums, rhythmic taps, voices just below intelligibility. At first, they try to explain it away as plumbing or soil settling. But the sounds grow clearer, more structured, as if something underground is trying to communicate. The deeper they listen, the more the boundary between recording and reality blurs, pulling them into a waking nightmare.
