Killian Scott has joined the BBC One thriller series The Capture in a "pivotal role" for its third season.
Created, written, and executive produced by the BAFTA-winning Ben Chanan, The Capture will see Holliday Grainger reprising her role as Rachel Carey - now opposite Love/Hate and Dublin Murders star Scott.
"I think Ben has created something really special with The Capture, a modern espionage thriller that feels both authentic and immensely captivating. I feel incredibly lucky to be joining the team for season three," said the Dubliner.
Teasing what's ahead in season three, the BBC said: "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 twelve 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 head of SO15 (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?"

"Other returning cast members include Indira Varma as BBC Newsnight presenter Khadija Khan, Ben Miles as Danny Hart, Lia Williams as Gemma Garland, Ginny Holder as DI Nadia Latif, Ron Perlman as CIA agent Frank Napier, Nigel Lindsay as DSI Tom Kendricks, Tessa Wong as DC Chloe Tan, and Daisy Waterstone as Abigail Carey," the BBC added.
"Joe Dempsie (Get Millie Black, Toxic Town, Game of Thrones), Andrew Buchan (Black Doves, Broadchurch, Better), Hugh Quarshie (Star Wars: Episode I - The Phantom Menace, Stephen, Holby City) and Amanda Drew (A Very British Scandal, The Gold, Gangs of London) also join the cast."
"I am delighted to join up with Holliday Grainger, Lia Williams, Ben Miles, Ron Perlman, and all our brilliant cast on The Capture again, and to welcome the fantastic Killian Scott to the fold," said writer-creator Ben Chanan.
"Previous seasons have seen Holliday's Rachel Carey investigate others as their lives fall apart. Most of all, I am excited that series three puts Carey at the heart of the conspiracy."
Filming of the six-episode season is currently under way in the southeast of England.
