The premise is deceptively simple: Ian Ridley (Brammall) is an emergency dispatcher - a guy who spends his shifts talking strangers through their worst moments. Then one night a frantic teenage caller comes through his headset, and something in her voice, her phrasing, her panic, convinces him she might be his long-missing daughter. What follows is a season-long obsession as Ian stops at nothing to find her.
That's the engine. The show wisely doesn't explain everything up front. We get fragments - a family fractured, a brother named Dean (Tobias Muhafidin) carrying his own weight, a wife, Sarah (Chloe Jean Lourdes), who has clearly learned to live inside the grief. Around Ian orbit Henry Reid (Brendan Cowell), Jenna Reid (Maxine Peake), Donald Reid (Daniel Henshall), Debbie Mcguire (Jessica Wren), and Isabel "Izzy" Pena (Zahra Newman) - a lineup of names that the series parcels out with real patience.
It's a crime drama, a mystery, and - more than either - a portrait of a man who never got to stop searching.
