Oh, the things people do and say in a conspiracy thriller… Some of them can make even the most innocuous conversation look like evidence of high treason. A whispered exchange here, a phone call there, and how can we forget those suspicious glances? All it takes is a few minutes to convince you that the entire government is plotting something. And as if Netflix didn’t already have enough of them, it’s now bringing us Trinity.

Now, remember Bodyguard? Because Jed Mercurio had us absolutely hooked back in 2018, with six episodes of Richard Madden’s David Budd navigating a political minefield where trusting the wrong person could literally get you killed. The series became a massive television sensation and went eight years without a second season. At this point, that’s just cruelty, and what did we ever do to deserve it?

But here’s some consolation, because the reunion we’ve been craving is finally happening, just not quite how we imagined. Netflix is bringing us Trinity with Madden and Mercurio back together, with Madden playing US Secretary of Defence Webb Preston alongside Gugu Mbatha-Raw’s naval commander Katherine Decker. And Mercurio has traded Westminster intrigue for a conspiracy involving nuclear weapons this time.

Netflix just dropped the trailer ahead of the December 1st premiere, and honestly, seeing these two reunite is already enough to pique our curiosity. So, what’s all this nuclear mayhem about, and who’s joining the cast? Here’s everything we know about Trinity!

What is Trinity about?

So far we know that there’s a nuclear submarine, and when there’s something that sensitive, a military blunder is just ready to happen. And all of it is incomplete about a sinister politician. Meet Commander Katherine Decker (Gugu Mbatha-Raw), second-in-command aboard the USS Kansas, whose encounter with US Secretary of Defence Webb Preston (Richard Madden) lands her smack in the middle of a conspiracy with potentially world-ending consequences.

Now, Katherine’s submarine comes very close to launching a nuclear weapon at an enemy that, well, isn’t even there. Yes, you read that correctly! Preston becomes rather interested in her version of events, and the two develop an unexpected connection.

There is also the small matter of his involvement in a mysterious classified programme called “Trinity”. So, is this man genuinely trying to stop World War III, or is he the very person Katherine should be running from? Well, Netflix isn’t telling us which side he’s on just yet, and that’s probably for the best.

Who is in the cast?

First up, we’ve got Gugu Mbatha-Raw, whom you’ll probably recognise from Loki, Surface and Black Mirror, leading as Katherine Decker. And opposite her? Richard Madden as Webb Preston, a technology-savvy defence secretary with massive political influence. And remember, Madden’s last collaboration with Mercurio on Bodyguard earned him a Golden Globe. So, expectations for this reunion? Oh, they’re understandably sky-high!

And the rest of the cast is quite the impressive gathering; thank you very much! Marcia Gay Harden, James Remar, and JD Pardo as Lieutenant Commander Tom Reyes, Bruce Greenwood, and Robert Wisdom are all set to add fuel to this fire.

When is Trinity coming to Netflix?

Everyone! Get December 1st marked in your calendars, because that’s when Trinity arrives on Netflix, and all seven episodes drop together! Yep, no agonising weekly waits. And if December 1st feels like an excruciatingly long wait, why not revisit Bodyguard on Netflix? After all, nothing prepares you for another Mercurio conspiracy like watching Richard Madden navigate one.
