When his vintage 1948 Zenith radio begins receiving an impossible transmission, seventy-two-year-old repairman Arthur Penhaligon is pulled into a hidden world of frequencies. Leaving his basement workshop, he discovers a secret bunker and a gateway to a dimension where sound has physical form.
There, he reunites with his long-lost father and his late wife, Martha, joining them as guardians of the "Source"—the foundation of all human communication. Together, they must defend the collective memory and emotional harmony of humanity against a shadowy corporate entity on Earth that seeks to weaponize fear through global static. Arthur’s journey takes him from a lonely technician to a cosmic conductor, proving that even in a world of digital noise, the most powerful signal is a human one.
