The Capture

With Pierson deemed MIA, Carey finally gains full control of SO15 and immediately releases Whitlock, leaving Figgis with no choice but to act. The Correction Inquiry hears a shocking revelation from Sir Rowan Gill, thrusting Garland into the glare of the world's media. Pierson takes the initiative and, with some help from Wizard, gets back on his feet.

E-Squadron go on the offensive, and Carey becomes entangled in an increasingly complex and dangerous situation. Every action she takes appears to have been predicted and premeditated. With few allies left to trust, sacrifice is inevitable – just how far is Rachel Carey willing to go to protect the truth?

Carey and Pierson escape into a network of underground tunnels as Pierson's past comes back to haunt him. Unarmed and with no back-up, Carey has no choice but to hear Pierson's story. She is horrified by what Pierson has been through and the extent of the conspiracy that they are now both entangled in.

Simon's real identity is revealed as Carey's allies above ground piece together the truth about Pierson. Carey forges an uneasy alliance to bring down the forces truly responsible for Isaac Turner's murder.

Carey is under pressure to charge James Whitlock, with Pierson keen for them to work together to close the case. Both soon find they have other problems to deal with, and Whitlock is left to Latif and Tan to 'break'.

Carey's inability to reach Napier leads to her facing the consequences of her actions, and through Danny Hart, an unlikely group of allies presents itself. Pierson is also facing the consequences of his actions and must convince his colleagues that he is fit for the job.

Meanwhile, an off-the-record military group known as ‘E-Squadron' seek advice from the mysterious Simon on how to get their plans back on track. Simon suggests ‘executive action', and a deadly trap is set for Rachel Carey.

Carey searches for one suspect, whilst Frank Napier deals with another. As the evidence mounts, and Carey is forced to avert another catastrophe, she begins to fear she might have made a terrible mistake. Not that Napier cares. He's using his own unique brand of interrogation to test Carey's theory.

Pierson's first day on the job gets ever more challenging, but as the net tightens for James Whitlock, it looks like SO15 might have made a breakthrough in the case.

More video evidence of the attack emerges, isolating Carey even further from those around her. With pressure building to find the assassin, Carey's assertion that SO15 is compromised gains little traction. Convinced that an insidious conspiracy is unfolding at the heart of the establishment, Carey takes matters into her own hands and seeks an unlikely ally in Gemma Garland. Meanwhile, Noah Pierson finds his first day at work more surprising than he ever expected...

Twelve months after exposing 'Correction' in the most dramatic circumstances, whistleblower Rachel Carey is back, ready to launch Operation Veritas, a revolutionary new camera network capable of catching live deep-fakes in action. With the home secretary Isaac Turner's support, the changes signal a new dawn in UK counter-terrorism policing. That is until a terror attack in central London sends shockwaves through the nation, leaving Rachel the one key eyewitness.

The net tightens. After DCI Carey is kidnapped, her instincts are proved right – but she's in more danger than ever before, while Isaac Turner pursues his own agenda.

Will Isaac Turner meet his digital doppelgänger? DCI Carey pursues a risky new suspect – will she finally find out who is behind everything?

DCI Carey investigates a TV hack amidst a growing media storm. Security Minister Isaac Turner finds himself engulfed in an unjust furore over Deepfake Isaac's racial profiling comments on TV, leading to him being expediently sacked by the Home Secretary. A major suspect in the hack is seen heading towards the airport and must be stopped before he leaves the country. The invisible assassins strike again, revealing the extent of which they are capable. Isaac plays a crucial role in the investigation, but a net is tightening, and the Operation Vanguard team suffer a tragic blow.

Isaac's paranoia intensifies in the wake of his hacked TV interview, and his family ties are put to the test when claims about his 'love child' become headline news. Reporters circle the family home, forcing Simone to leave with their children – after which Isaac's outburst against the media is filmed and goes viral. Isaac's digital doppelgänger sets up an interview for him on BBC Breakfast, during which the results come in for his paternity test. S015 widen their search for the invisible assassins and recalibrate their thinking as to who might be behind the attacks. Garland discovers a new perspective on the CIA's Frank Napier and Carey feels the net tightening around her as allegiances buckle and shift.

DCI Rachel Carey is living a lonely, paranoid existence, struggling with thwarted ambitions while seconded to Counter Terrorism Command's 'mapping' department. She's officially joined the highly classified Correction team, but has yet to be truly let in.

When her former colleagues DS Flynn and DI Latif bring the case of a man murdered by invisible assailants to her attention, the stakes quickly become deadly. Carey's investigation brings her into the orbit of hotshot politician Isaac Turner MP as the case's links to national and international security start to emerge. Something is very wrong, but can she work out what before Britain's security is irrevocably compromised?

And which of her colleagues can she trust?

Security Minister Isaac Turner's hacked TV interview sends shockwaves through his personal and professional life, as he struggles with an increasingly fractured reality and discovers the dark secret that is Correction.

SO15 work to contain the facts of the broadcast hack while trying to uncover the bigger picture themselves. With DS Patrick Flynn in hospital, DCI Carey and the team investigate a web of politically charged clues which seemingly lead to China. As the ongoing investigation provides more questions than answers they tread carefully, interrogating every assumption and allegiance.

Meanwhile, Isaac Turner tries to clear his name by booking himself onto Newsnight for a fresh interview, only to find himself walking into a new trap.

Carey's investigation widens and she makes several important new allies... but can they be trusted?

Carey teams up with Shaun Emery to try and expose Correction, but Napier is one step ahead. Shaun's future, and that of the nation's system of justice, lie with one person. Carey has a decision to make.

Neither Carey nor Shaun are prepared for what lies ahead, as the truth, in all its complexity and ambiguity, is revealed to them.

Carey develops a theory as answers begin to reveal themselves, and Shaun finds himself trusting an enigmatic stranger who promises to lead him to the truth.

The stakes intensify for Shaun when he comes face to face with inscrutable CIA agent Frank Napier, whilst Carey's investigation appears to hit rock bottom.

After key evidence is mysteriously redacted from her investigation, Carey is forced to find other ways of pursuing Shaun, who is searching for answers of his own.

When soldier Shaun Emery's conviction for a murder in Afghanistan is overturned because of flawed video evidence, he returns to life as a free man with his young daughter. But when damning CCTV footage from a night out in London comes to light, Shaun's life takes a shocking turn and he must soon fight for his freedom once again.

With newly promoted DI Rachel Carey drafted in to investigate Shaun's case, she quickly learns that the truth can sometimes be a matter of perspective. Should she trust Shaun Emery?
