About
"A time-crossed father-daughter mystery with real heart"
Frequency follows a present-day NYPD detective who discovers she can talk to her dead father through an old ham radio, thanks to a freak solar event linking 1996 and today. Their late-night conversations start rewriting both timelines, pulling them into a decades-old serial-killer case that threatens the people they love. The show blends time-bending mystery with an earnest father-daughter reconnection story, moving at a brisk, twisty pace. It leans more character-driven melodrama than hard sci-fi, carried by sincere performances, though the ripple-effect plotting occasionally strains credulity if you think too hard about the rules.
