Ruth Wilson narrated the first three episodes in 2017; Indira Varma took over from 2018 onward. Each instalment tracks one or more cases from the moment a 999 call is logged through to whatever conclusion the evidence permits. Cameras travel with officers from Cheshire, Greater Manchester, North Wales and other forces as they draft search grids, knock on doors, trawl CCTV and brief increasingly anxious relatives in kitchens lit by fridge doors at 3 a.m.
The programme withholds narration until the final third, letting radio chatter, phone footage and corridor conversations carry the story. A 2020 episode follows a 79-year-old dementia patient who boards the wrong bus; another from 2022 centres on a teenager last seen on Snapchat in a park after dusk. When bodies are recovered the screen cuts to black, then white text confirms identity; when people are found alive the update arrives via a simple doorstep handshake.
Four series have aired, totalling fifteen hour-long episodes produced by Blast! Films. The third run lost its final episode to legal objections, a gap the broadcaster has never explained. The fourth series, broadcast in October and November 2022, drew an average overnight audience of 4.1 million viewers.
