The Capture's Major Twist: Killian Scott Explains the Shocking Assassination Plot
The BBC's critically acclaimed drama The Capture has returned with a third season, delivering a jaw-dropping twist that has left viewers reeling. The series, which explores the dangers of deepfake technology known as Correction, premiered its latest episodes on Sunday, 8 March 2026, immediately plunging protagonist Rachel Carey into a nightmarish conspiracy.
A New Season of Paranoia and Deception
The narrative picks up one year after the events of season two, with Holliday Grainger's character Rachel Carey now serving as the Acting Commander of Counter Terrorism Command. The UK intelligence service is under investigation for its unlawful use of the Correction programme, which Carey previously exposed. Meanwhile, new camera systems have been implemented to detect Correction in real-time, adding a layer of technological tension to the plot.
In a dramatic turn, MP Isaac Turner, portrayed by Paapa Essiedu, has risen to the position of Home Secretary and is poised to become the next Prime Minister. However, his political ascent is brutally cut short when he is assassinated during a public speech, witnessed directly by Carey. The assassin, played by Killian Scott, points his weapon at Carey before inexplicably sparing her life and escaping the scene.
The Ultimate Paranoid Freak Out
When security footage is reviewed, Carey is horrified to discover that the assassin's identity has been completely altered through Correction technology. Instead of Scott's character, the video shows an unknown individual played by Joe Dempsie. This manipulation leaves Carey as the sole witness to the truth, trapped in what Scott describes as "the ultimate paranoid freak out."
The twist intensifies when Carey meets her replacement as Commander of Counter Terrorism Command: the very assassin she saw murder Turner. Scott's character is now her superior within MI5, creating an impossible dilemma where Carey must convince others that the man they have hired is actually the killer they are hunting.
Killian Scott on the Polarising Role
In an exclusive interview, Scott discussed the challenges of his dual role in the series. "I have two entrances in episode one, and they're polar opposites in terms of who I am, and certainly as far as Rachel Carey and the audience are concerned," he explained. "Everyone else in the show is unaware of what takes place. In terms of the assassination, they all think it's Joe Dempsie because it's Joe Dempsie’s face. Poor Joe is getting thrown under the bus!"
Scott emphasised the central conflict of the season: "I'm head of intelligence now within MI5, and yet as far as she sees me, I've assassinated the guaranteed next prime minister. So what happens between those two things, and how can both things be true? That is the big conundrum for Rachel this season."
Despite the adversarial circumstances, Scott hinted at a complex dynamic between the characters. "They sort of need to operate as something of a team," he noted, but acknowledged Carey's isolation. "She’s certain of what she has seen, but no evidence can corroborate that, and no one else can plausibly believe her because they see all the footage and then they see me and they're like, ‘This is just two different people.’ They think she’s had a traumatic experience and therefore things have not processed properly."
Future Revelations and Series Details
Scott also teased an upcoming revelation regarding why his character spared Carey's life. "He hesitated for reasons that no one needs to know just yet – there is a reason and the audience will find out," he revealed, promising further twists in the episodes ahead.
The Capture, which first aired in 2019 and returned in 2022, continues to be available for streaming on BBC iPlayer, with new episodes airing weekly on Sundays. The series has been praised for its gripping exploration of surveillance, truth, and technology, solidifying its reputation as a must-watch thriller.
