Holliday Grainger is reprising her role as Rachel Carey in the third season of BBC's The Capture after a lengthy four-year gap since the second season. The upcoming season continues to explore the implications of deepfake technology, specifically focusing on the illegal manipulation of video evidence known as Correction. This season is set 12 months after Cary's character's pivotal moment of exposing the UK’s secret video manipulation program to the public by broadcasting a deepfake of a government minister.

In discussing her character’s journey, Grainger describes Rachel Carey as an ambitious and determined officer in the Metropolitan Police, who is navigating the challenges of her career alongside the moral complexities that arise from her discovery of Correction. As the story unfolds, the character's arc showcases the tension between career aspirations and ethical dilemmas, highlighting the real-world consequences of technological advancements in video and information manipulation.

The return of The Capture not only revives Grainger’s character but also symbolizes the show's commentary on contemporary issues surrounding privacy, surveillance, and the potential misuse of technology in society. As audiences await the series' debut, there is a significant anticipation regarding how this new narrative will reflect ongoing dialogues about trust in media and the integrity of information.
