A badly decomposed body is found inside a suitcase lying beside a railway embankment in Exeter. Police begin a hunt for the killer, with the only lead being CCTV footage captured near the site, giving them no other clues to follow.

is a television episode that falls under the programme genre. It presents a self‑contained story centred on a single, unsettling discovery, and it is structured as a typical crime‑focused instalment. The narrative kicks off when officers locate a severely decomposed corpse hidden inside a suitcase lying beside a railway embankment in Exeter. The find sets the investigation in motion, and the detectives are left with little more than CCTV footage to chase down the person responsible. Their search hinges entirely on what the cameras captured, as no other leads are mentioned. The episode concentrates on the police effort to piece together the events that led to the body being concealed in that remote spot. With the only clue being the surveillance recording, the investigators must scrutinise the visual evidence for any hint of the perpetrator’s identity or movements. The story therefore revolves around the tension of working from a single, limited source of information while trying to bring the case to a conclusion.
