Brand new five-part drama set in Northern Ireland following a PSNI investigation into a string of recent homicides. When the PSNI are unable to close the case after 28 days, Detective Superintendent Stella Gibson ( Gillian Anderson) of the Metropolitan Police Service is called in to review the case. Under her new leadership, the local detectives must track down and stop the serial killer who is terrorising the city of Belfast.
After completing his night shift, Olson arrives at the hotel where Gibson is staying. As they make love, we see Spector indulge in his own fantasy, cleaning and posing a new victims lifeless body. After cutting a lock of her hair and taking an item of jewellery he poses and photographs her before slipping out unnoticed. The next day, Gibson arrives at work to be confronted by Burns wielding an article by Ned Callan questioning the police’s investigation, all on the morning that Burns has to face Morgan Monroe and the policing board. Gibson brushes it off, more interested in reviewing the recording of Aaron Monroe’s interview and examining the drugs found at her home with DS Mary McCurdy.
Ferrington and Stone are the first officers to react to the emergency radio dispatch, and instantly recognise the address. As Stone leads Marion away from the house, Ferrington slowly enters the bedroom and has her worst fears realised. As Martin arrives and takes charge of the scene, Gibson too gets word and appeals to Burns to let her take over the case. Gibson is joined by pathologist Prf. Reed Smith and together they go about making their initial investigation. Across the city, Aaron Monroe is entertaining some foreign businessmen with a party of cocaine and hookers, all under the protective watch of a moonlighting Rob Breedlove.
Meanwhile, at Spector’s house, Sally Ann is surprised to find Katie at the front door. Claiming she is hear to copy some of Paul’s music, Sally Ann lets her in as she heads off to work. As Katie looks around Spector’s study, she opens one of his drawers and finds the lock of a victims hair.
