When the world is gripped by a silent plague, language becomes a deadly weapon. Three hundred hertz. A frequency inaudible to humans awakens from an experiment sealed away twenty years ago and broadcasts continuously around the globe via satellite. Day after day, it seeps into every conversation, every song, every cry, infiltrating the human language centers like a slow-acting poison.
Within hours, the infected lose their emotions, their sense of self, and the desire to speak. They no longer feel anger or sadness, and they no longer love. They silently pursue every sound: ambulance sirens, television broadcasts, even a whisper. They become the quietest ghosts in a silent city, moving in swarms, resonating at the same frequency like puppets pulled by a single string.
If the apocalypse is silent, your only weapon is to keep quiet. Silence is not surrender. Silence is the last resistance.
