"Can you hear it? It's counting down to you."Mark, a disgraced audio engineer seeking solitude, accepts a posting at a remote listening station deep in the Alaskan wilderness. His job is simple: monitor the static of forgotten Cold War frequencies. But in the crushing silence of the Arctic, he picks up something that shouldn't exist-a repeating signal on a dead frequency.Signal 39.It starts as a child's voice reading numbers, followed by the terrifying sound of hundreds of people screaming underwater. As Mark isolates the transmission, the signal begins to isolate him. The arctic wind starts to mimic human voices, the station's machinery breathes in sync with his own lungs, and he begins to lose hours of time, waking up with nosebleeds and the taste of saltwater in his mouth.When he discovers the journal of the previous operator-who didn't just quit, but vanished into the ice-Mark realizes the signal isn't a distress call. It's a containment breach alarm from something buried beneath the station. And the countdown is almost over.A claustrophobic descent into auditory madness. 'Signal 39' is a chilling psychological thriller about the sounds that survive in the dark.
