Warning: Major spoilers for The Capture's Season 3 finale below!
The first episode of The Capture's third season started off with a bang — literally. A year after the televised deepfake reveal in Season 2's finale, acting Commander Rachel Carey (Holliday Grainger) shares a warm catch-up session with politician Isaac Turner (Paapa Essiedu), who's a top contender for Prime Minister. Turner is assassinated minutes later in the first, but far from the last, shocking character death of the six-episode season.
By the end of Episode 6, we learn there are far scarier actors out there than CIA agent Frank Napier (Ron Perlman) and the international plot known as Correction that deepfakes footage of crimes. The newest Big Bad is a predictive AI model named Simon that military higher-ups have ceded their power—and thinking—to.

Season 3 also introduced us to a new character meant to replace Carey as Commander, Noah Pierson (Killian Scott). Or at least, he was known to some as Noah Pierson.
So how did The Capture end? Read a full explanation below, where we've answered your pressing questions. Stream all three seasons of The Capture on Peacock now.
How did The Capture Season 3 end?
Thanks to Carey, Noah Pierson survived ripping out his own heart monitor and is recovering in a safe house (anyone else detect chemistry between Carey and Pierson?). Grilled by Danny Hart (Ben Miles) and DSU Gemma Garland (Lia Williams), Noah explains that Simon wanted Isaac Turner dead due to events it predicted would happen if he became Prime Minister. Rachel and Pierson question what Danny and Gemma know about the fall guy for the assassination, James Whitlock (Joe Dempsie), but they're cagey.
The Correction hearings roll on, and former British Home Minister Rowan Gill (Andy Nyman) publicly outs Gemma as the mastermind behind the deepfakes program. Rachel is kidnapped from a military convoy and brought to Colonel Figgis, who shows her a live feed of her sister Abigail (Daisy Waterstone) held at gunpoint. Figgis says they'll kill Abigail if Rachel doesn't have James Whitlock re-arrested for Turner's murder per Simon's request — and then they shoot Abigail, or is it another deepfake?
Why did Noah Pierson kill Gemma Garland?
Correctly sensing Carey's been abducted by his E squadron, Noah leaves the safe house to "save her." But just as we think we're about to see Noah swoop in to save Rachel from getting shot, another jaw-dropping twist: he busts into the hearing and executes Gemma in front of everyone. "Corrected" footage showing James Whitlock as the assassin is circulated immediately while the real James Whitlock is killed in his own home. "Simon says thank you," a man tells Whitlock before he fires.

Rachel finds Noah in the tunnels and shoots him, knowing he killed Gemma. As he dies, he tells Rachel, "I was surprised as anyone. I was coming to save you." Unfortunately, Simon had issued Noah a mission to kill Gemma because the public would assume her death spelled the end of Correction. Noah's fulfillment of the mission is why Rachel was spared when she was abducted. "You see Rachel, I did save you in the end," Noah sputtered before dying. Uh, maybe you could've called for help sooner, Rachel?!
Meanwhile, Rachel busts her aide Paige for assisting in the Correction of Turner's murder, having figured out she's been blackmailed by a "mole" journalist named Natasha who's colluding with Simon. In order to er, correct the original Correction that deepfaked Whitlock shooting Gemma, Rachel releases her own Correction depicting what really happened. Gemma would be proud, but Rachel's team isn't.

As a final ace in the hole, Figgis and the rest of Team Simon release new disinformation about Noah Pierson. Figgis surprises Rachel at work to tell her she accidentally assisted in a plot to cast all blame on Russia. "What's your endgame? Simon says World War Three?" she asks.
"We asked Simon what it would take for Rachel Carey to use Correction," Figgis tells her. We've now witnessed the answer play out.
The penultimate scene in the finale finds many of the powerful men in Season 3 meeting to toast to a job well done — including Figgis, Commissioner Yates who gave Noah Pierson the job of Commander, former Home Secretary Nyland, and even the man overseeing the Correction hearings.
Is Gemma Garland really dead? Why did Rachel see her?
At the very end of The Capture Season 3, Rachel shares a vulnerable moment with her very-much-alive sister Abigail. Rachel then looks at a selfie they've snapped on her phone, only to find Gemma Garland (aka Jacqueline Goldcross) looming outside on the deck behind them.
Is there a chance Gemma lived?
"Well, that’s the question, isn’t it?" Holliday told Cosmopolitan UK. "I mean, do you believe what you see?"
Just as Rachel saw Noah kill Turner with her own two eyes, we saw Noah shoot Gemma through the head, making it nearly impossible that she survived. So it's safe to say this is most likely someone (or something, aka Simon) sending a doctored image to mess with Rachel.
Who was Noah Pierson, aka William Walker? Is he really dead?
Carey's quest to expose her new boss Noah Pierson as Isaac Turner's assassin — despite everyone's insistence her eyewitness account must be wrong — led her to his true identity.
Pierson claims he's actually Captain William Walker of United Kingdom's Special Forces. A highly trained soldier, Walker killed Turner at the orders of Colonel Figgis (Linus Roache) and Figgis' AI boss, Simon.
With an implant in his heart to keep him compliant, Walker received a new mission from Simon immediately after assassinating Turner: Assume the identity of Noah Pierson to take over Rachel's acting Commander role. Except the relentless eyewitness Rachel foiled that plot.
Eventually, Noah/William tells Rachel that he couldn't shoot her when he killed Turner because she resembled a refugee he couldn't save while on active duty. He's unable to again during his final deadly standoff with Rachel, and dies because of it. Noah/William is not a Russian spy as the media claims after his death; that's another machination of Simon's to protect their operation. We have no reason to believe he is still alive.
Is Ron Perlman's Frank Napier really dead?
Yes — we see proof of it after his body is discovered following his death at Noah's hands. Sadly, Paapa Essiedu's Isaac Turner is also definitely dead in what was one high-body-count season.
Will there be a Season 4 of The Capture?
As of June 2026, there has been no confirmation of a Season 4 renewal from the BBC, who produces the show. But stay tuned for updates — and again, you can stream all three seasons of The Capture on Peacock anytime.
