Trigger Point Show Summary, Upcoming Episodes and TV Guide

The EXPO team are stretched to breaking point dealing with a complicated device planted at the Campaign HQ of the Progressive Alliance. Lana tells Karl she wants to break up.

Sonya manages to trace the chemical explosive HMX used by the bombers to a government lab at Porton Down, but runs up against a wall of silence when she pushes for more information. Lana demonstrates to Thom that the wiring within the devices shows evidence of advanced bomb-making skills, leading her to suspect members of her own team.

CCTV footage of a suspicious vehicle leaving Westhaven leads Washington and the team to a warehouse on the edge of London, where they uncover bomb-making materials and evidence that seems to confirm that the bombers were Islamist. But the discovery of what appears to be military equipment and high-grade explosives on site makes Lana question the real identities of the bombers, and a further device left in a sensitive and provocative location seems to confirm her suspicions.
