Joaquin, the hip, melancholy host, sits deep in a fog of cigarette smoke, fielding calls from believers and detractors alike. He is joined in the booth by his darkly beautiful girlfriend, Alondra, and his engineer, Watts. Originally an underground cult sensation, Ghost Radio is primed to break out to mainstream audiences when a huge radio conglomerate offers to syndicate the show. As Ghost Radio becomes a national hit with an expanding legion of hardcore fans, neither Joaquin, Alondra, nor Watts is remotely prepared for what is about to happen.

When Joaquin starts noticing a curious and troubling phenomenon drifting into his broadcasts, he is inexplicably drawn further and further into the terrifying stories he solicits on the radio. As he slowly loses control over his reality and finds himself unable to distinguish between the real world and the world populated by the nightmares on Ghost Radio, he’s forced to confront his past and his own mortality in order to repair the crumbling wall between the living and the dead.
