As fans of The Rookie await the beloved police procedural’s Season 9 premiere next year, the BBC may have the perfect replacement series, which officially returns to the U.S. soon for Season 4. Set in Belfast, Northern Ireland, the British drama follows three probationary officers — Grace, Tommy, and Annie — with the Police Service of Northern Ireland (PSNI). Like The Rookie, they’re initially paired with experienced officers who train, mentor, and work alongside them.

Titled Blue Lights, the BBC series is an underrated cop show with zero bad episodes. It recently returned for its fourth season in the U.K. and will arrive in the U.S. on BritBox on November 12, with new episodes released weekly through the December 17 finale. Ahead of the U.S. launch, BritBox has dropped an official trailer teasing higher stakes for the former rookies, as controlling Northern Ireland’s ongoing drug pipeline only gets harder.

Watch the Blue Lights Season 4 trailer below.

Four action series. One of them is built around exactly the way you
handle pressure, people, and a room that has just gone very quiet. Here is where you would survive
the trilogy, and probably headline it.

You are precision with a grudge. You don’t posture, you don’t
escalate, and you don’t warn anybody twice. That is exactly why the people who know you are
so careful never to be the reason you start.

The Wick films run on discipline: an underworld with actual etiquette, a hero who
honours every rule of it, and a world that unravels the instant someone breaks one
against him.
You share that quality. You are extraordinarily reasonable right up to the line, and
then completely immovable past it.
Focus, commitment and sheer will. You’d be the one carrying grief through three sequels
and turning it into technique rather than noise.
People wouldn’t call you dangerous. They’d say your name quietly and let that do the
work.

You understand the thing the whole franchise is secretly about:
the cars are spectacular, but the crew is the point. You collect people, you keep them, and
you’d drive through a building for any one of them.

This series went from street racing to orbit without ever changing its actual subject,
because loyalty scales and plot doesn’t have to.
You have the same instinct. You build a family out of whoever turns up, and then you
defend it past the point of reason.
You’d thrive here because the franchise rewards exactly your strengths: warmth, nerve,
an absolute refusal to leave anyone behind, and a relaxed relationship with physics.
The mission can wait. The barbecue cannot.

You over-prepare and then take the dangerous part yourself
anyway. It looks like control, but it’s really responsibility. You have never worked out how
to ask somebody else to carry the risk.

This is the franchise of the plan that collapses on schedule: the team, the mask, the
rooftop, and the one person sprinting flat out because sprinting is all that’s left.
You share that refusal to accept an outcome. Told the odds, you treat them as an
administrative error.
You’d thrive here because these films reward competence and loyalty in equal measure.
The mission matters, but nobody on the team gets left on the wrong side of a door.
Some people delegate the cliff. You have never once been that person.

You are not the most trained person in the building, the best
equipped, or the one anybody would have picked. You are simply the one still standing at the
end, which turns out to be the only qualification that matters.

Die Hard invented the modern action hero by making him mortal: outgunned, out-planned,
bleeding, and extremely funny about it.
You share that stubbornness. Adversity doesn’t make you noble, it makes you sarcastic,
and then it makes you unstoppable.
You’d thrive here because these films reward improvisation and nerve over preparation,
and you’ve never had the luxury of preparing anyway.
You didn’t want any of this. You just declined to be the person who let it happen.
