Over the course of three days, eight government officials, a Member of Parliament, and a political appointee participate in a war-game which has taken place regularly among British civil servants since the 1960s, as a way to help them formulate government procedure in the event of nuclear war. In the depicted meetings, set in 2014, the group discusses possible UK policy in the fictional event of a nuclear detonation in Mumbai, India by a Pakistani organisation.
