Fans of British thriller series ‘The Capture’ have been eagerly awaiting Season 3 as it promises to deliver more tension, more conspiracy, more blurred lines, and more shocking plot developments based on the dark & disturbing technology of video manipulation. Only Season 2 had just recently finished airing when Episode 1 of Season 3 aired, coinciding with the explosive events that happened in the last episode of Season 2.
In April 2025, the BBC announced that The Capture had been officially renewed for a third season. Filming for Season 3 of The Capture began around the same time, and is now set to premiere in spring 2026 via BBC One and on-demand via BBC iPlayer.
The BBC has not released an official premiere date for Season 3 at the time, but the “Spring 2026” label indicates anything from March through to May or early June. The BBC has announced that additional content is being provided on their iPlayer service to prepare for the release; specifically, Seasons 1 and 2 will be made available on iPlayer starting 13 February 2026.
The first teaser trailer released on iPlayer indicates that the third season’s overarching narrative will follow a darker, more technologically complex path and continue to play off the show’s central themes: deepfakes, surveillance, and manipulated reality.
The Capture Season 3 Expected Cast
Holliday Grainger will reprise her role as Rachel Carey, who was promoted to Acting Commander of Counter Terrorism Command (SO15) and can now be seen dealing with the aftermath of last season’s explosive finale. Especially Essiedu returns as Isaac Turner MP, whose role was essential in exposing the Correction programme.
Also returning are Indira Varma (Khadija Khan – Newsnight), Ben Miles (Danny Hart), Lia Williams (Gemma Garland), Ginny Holder (IN Nadia Latif), Nigel Lindsay (DSI Tom Kendricks), Ron Perlman (Frank Napier – CIA), Tessa Wong (DC Chloe Tan), Daisy Waterstone (Abigail Carey) and Andy Nyman (Sir Rowan Gill).
New for Season 3 is the addition of Killian Scott in a major role, along with Joe Dempsie, Andrew Buchan, Hugh Quarshie, and Amanda Drewadding greater political and institutional depth to the storyline.
The Capture Season 3 Potential Plot
After a year has passed from Season 2, Season 3 will be placed in a position where Rachel Carey operates as the highest-ranking official in UK Counter Terror Policing after she acted like an actual agent through a live deepfake video during which she revealed the Intelligence Services have been secretly manipulating video files for some time. The public inquiry to determine whether or how such a program was unlawfully used is ongoing, and the public trust in surveillance technology is at an all-time low. Rachel will attempt to restore public trust in video surveillance through the establishment of a new camera system known as Operation Veritas.
As previously teased in the promotional material, Season 3 will delve even deeper into the threats posed by deepfake technology, which will make it much more difficult to validate the authenticity of truth and to use perception as a weapon against other people or organizations.
Throughout the 6-episode run of Season 3, you should expect to see elements of political conspiracy and power struggles, escalating ethical dilemmas around credibility, integrity, governance, and control — continuing the show’s long-standing tradition of containing stand-alone stories during each season while also developing into a single-rank episodic series.
