Emmy and Golden Globe winner Gillian Anderson (The X-Files) delivers a masterful performance as steely DS Stella Gibson in this heart-pounding psychological thriller. Called to Belfast to investigate a high-profile murder, Gibson quickly realizes that a serial killer prowls the city. The culprit is Paul Spector (Jamie Dornan, Fifty Shades of Grey), a grief counselor and family man driven by vicious compulsions. As Gibson closes in on Spector, both the hunter and the hunted outmaneuver each other in a sinister game of cat and mouse. Will Gibson make Spector pay for his crimes before the death toll rises? An "intelligent show with tremendous acting" (The Atlantic), critics rave that "Anderson is sublime, almost otherworldly, while Dornan... matches her for icy charisma" (Daily Mail, UK). This complete collection of the award-winning drama also stars Archie Panjabi (The Good Wife), John Lynch (In the Name of the Father), and Colin Morgan (Merlin, Humans).
