The Capture | Series 3 Preview (BBC One)

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 (Holliday Grainger) 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?

The new series also features returning cast members Paapa Essiedu as Isaac Turner MP, Indira Varma as Newsnight presenter Khadija Khan, Ben Miles as Danny Hart, Lia Williams as Gemma Garland, Ginny Holder as DI Nadia Latif, Nigel Lindsay as DSI Tom Kendricks and Ron Perlman as Frank Napier.

Killian Scott, Joe Dempsie, Andrew Buchan, Hugh Quarshie and Amanda Drew join The Capture series three, alongside returning cast Tessa Wong (DC Chloe Tan), Daisy Waterstone (Abigail Carey) and Andy Nyman (Sir Rowan Gill).

The Capture returns Sunday 8th March at 9pm on BBC One.
