The idea of ITV’s Trigger Point is beautifully simple: a serial killer who uses bombs. It’s a clever device for extracting maximum tension – each episode featuring a ticking clock – but how do you keep things going for a second series? Or a third? Surely Britain doesn’t have that many crazed terrorists for the bomb disposal experts (EXPO) to chase? The answer to this conundrum is as simple as the show’s premise: you don’t worry about it! And so we arrive at the third season of Trigger Point, which returns this week.
A taxi is discovered on a disused industrial site, prompting fears it may contain explosives. But when bomb disposal expert Lana Washington (Vicky McClure) arrives on the scene, she discovers that there is also a mysterious passenger, and a note bearing the slogan “CONFESS OR DIE”. After finding the car is rigged with chemical weapons, the police realise that they are – once again – on the trail of a serial bomber. But who is he, and what is his grievance with the victims? Quickly, the trail spreads and historic wrongs are brought to the surface. “Let justice be done,” the shadowy perpetrator (played by Lock, Stock and Two Smoking Barrels’s Jason Flemyng) hisses. “Let the truth come out.”
