In a world ravaged by war, Rex, a lone radio DJ, broadcasts into the void, clinging to the desperate hope of finding another survivor. Day after day, his voice echoes through the desolate wasteland, a beacon in the deafening silence.
Then, one day, a faint signal pierces the static. Ecstatic, Rex believes he's found another human soul. But as the crackle resolves into a chilling language, a horrifying truth dawns - humanity might be extinct, and Rex's broadcasts have reached far beyond the ravaged Earth.
