On the edge of a remote desert town of Devonpeak, an old radio astronomy tower stands alone against the endless horizon. Sam Prentice, a reclusive radio astronomer, has exiled himself, spending his days listening to the quiet hum of the stars. The tower has become both his sanctuary and his prison, a place where the vastness of the cosmos keeps the ghosts of his past at bay. But when an impossible transmission emerges from the static followed by a series of unsettling events, it shatters the silence, forcing Sam to confront what he buried long ago and the only chance he has to redeem himself.
