WAR BOOK takes place over three days as nine civil servants gather in a government building to take part in a policy shaping scenario. They are there to take decisions on Britain’s reaction to an international nuclear attack. At first the participants are casual, playing out the scenario against a backdrop of their own petty squabbles and personal ambitions. Only two participants know the truth - that the country is secretly facing a real nuclear threat, and that their theoretical responses may become reality sooner than they can know.

As the scenario escalates and the group begins to address the breakdown of civil order, the reality that they are deciding our futures dawns. When personal politics crash irrevocably into the room, each is forced to look closely at what they really believe, and how much their decisions are actually worth.
