This docudrama from This World tells the story of a terrorist group planning what’s known as a Marauding Terrorist Firearms Attack (MTFA).

It follows a fictional young man who, while in prison on drugs charges, is recruited and radicalised by an Islamic extremist – and tracks the police investigation into the IS-inspired group planning the attack.

How UK agencies are working to keep us safe from such attacks is the subject of this film, which also features former Head of Counter Terrorism Richard Walton.
