MI5 agents in the field are in danger as the MI5 computers are being repeatedly hack by cyber terrorists.

Suspicion falls on Gordon Blaney, a member of a socialist anarchist group with a violent past. Zoe goes undercover as a teacher in a school that Blaney works in. She finds that he is just a mild mannered and dedicated teacher.

Danny goes undercover at a small socialist newspaper to find out if they have any links with cyber hacks. Danny finds that they are just paranoid nobodies.

Harry Pearce finds that the cyber attacks are linked to a dead field agent and someone traumatised by it.

I think the editing made it easier to work out the culprit in this one. The portrayal of the damaged person was done well.
