Trigger Point is returning to ITV for its fourth season later this year, with fans nervously awaiting the next nerve-shredding trials for Lana Washington (Vicky McClure).
The bomb disposal expert has pulled off some miraculous rescues in her time on the force, but she's also suffered some devastating losses – including some very close to home.
From wayward brother Billy (played by House of the Dragon's Ewan Mitchell) to one-time beau Thom Youngblood (Adolescence's Mark Stanley), attackers have targeted Lana at every opportunity.
Still, she won't be cowed, continuing to serve the general public with her steely nerve, which compels her to wander into devious death traps in each and every episode – but the latest trailer hints that she could be reaching the end of the line.
If you're excited for Trigger Point season 4, read on for everything we know about the new episodes so far, including release date speculation and that tense teaser.
Trigger Point season 4 does not yet have a confirmed premiere date on ITV1 and ITVX, but the hit crime thriller seems poised for an imminent return.
ITV gave the Vicky McClure series a high-profile showcase during its recent coverage of the FIFA World Cup 2026, so the broadcaster clearly is hoping to draw a large crowd to this latest pulse-pounding chapter.
With the marketing campaign beginning to pick up, it's possible that the show is eyeing a launch date in August or September – after the World Cup final, and in time for the influx of new programmes that autumn typically brings.
Of course, that's just speculation for now. We'll update this page when concrete details emerge regarding Trigger Point season 4 release plans.
