BBC unveils extended first look at one of its best thriller shows’ new season

"How do you protect the truth, in a world where lies are daily currency? And with the proliferation of deepfakes, how can we trust what we see?

"It’s been 12 months since Rachel Carey broadcast a live deepfake of a government minister to the nation, exposing the UK intelligence service’s clandestine video manipulation programme known as Correction.

"Amidst an inquiry into the unlawful use of Correction, Carey has become Acting Commander of Counter Terrorism Command, determined to regain the public’s trust in surveillance technology through the new Operation Veritas camera system.

"And then it happens: a brutal and exceptionally well-coordinated act of terror aimed right at the heart of the British establishment that leaves behind just one witness.

"The more Carey investigates, the deeper she is drawn into an unfolding geopolitical crisis that infects the British political establishment, the security services, and the media. The conspiracy reaches deep into the State, but just who is pulling the strings?

"Caught in an increasingly violent situation, and with few allies left to trust, what sacrifices will Carey be willing to make?"

Alongside Grainger, other returning cast members include Andy Nyman (Ghost Stories), Ben Miles (The Crown), Daisy Waterstone (Prime Target), Ginny Holder (Death in Paradise), Indira Varma (Game of Thrones), Lia Williams (The Missing),  Nigel Lindsay (White Gold), Paapa Essiedu (Gangs of London), Ron Perlman (Nightmare Alley) and Tessa Wong (Black Mirror).

Love/Hate actor Killian Scott will also be joining The Capture for its season three in a "pivotal role". This is alongside other newcomers Amanda Drew (The Gold), Andrew Buchan (Black Doves), Hugh Quarshie (Star Wars: Episode I), Joe Dempsie (Get Millie Black), Jonathan Aris (Vivarium) and Linus Roache (Mandy).
