To prove to the government that other people need help

The story follows a diverse cast of characters: a skeptical scientist who believes there's a logical explanation, an elderly woman who claims the hum speaks to her, and a young family whose child begins to communicate with the sound. As the hum grows louder, so does the paranoia. Sleep becomes a luxury, tempers flare, and bizarre accidents start to occur, each one seemingly linked to the omnipresent noise.
