Trigger Point — Season 3

Explosives Officer Lana Washington and her team are called to investigate a suspected bomb threat – an iconic, London Black cab that's been abandoned in a wasteland. However, they soon realise they're at the site of something far more sinister. Working alongside her colleagues in Counter Terrorism Command, the team race to find out what the person behind this unique bombing campaign wants, who they are, and who they might be targeting next…

With two incidents appearing to be connected, Counter Terrorism police work to establish a link between the two victims – a retiree and a university lecturer. As the investigation continues, the team grow suspicious that they aren't being told the whole truth, and an intervention from DS Helen Morgan backfires, leaving the unit at a loss.

With the help of Lana, Counter Terrorism Command learn more about the recent murders. But their progress doesn't go unnoticed by the bomber, whose campaign only intensifies, putting more people in grave danger.

All hope looks lost for the remaining missing person, until a new lead emerges. With Lana now known to the bomber, she has to work harder than ever to avoid falling into his traps, pushing her to breaking point.

The bomber's next target is symbolic of their whole campaign, and Lana, rushing against the clock, must find the bomb amongst the pandemonium. Her search peels back the layers of the bomber's secrecy, yet the two of them are thrown into new territory that neither is prepared for.

After the last attack, and with breakthrough evidence, Counter Terrorism police are close on the bomber's heel. Lana faces a reckoning when she uncovers the truth behind the campaign, as the confession so desperately fought for finally comes out.
