The diplomatic maneuvering and events involving those in authority are set in a fantasy location inside the pierhead pavilion, far from the trenches. In the opening scene, various foreign ministers, generals and heads of state walk over a huge map of Europe, reciting actual words spoken by these figures at the time. An unnamed photographer takes a picture of Europe's rulers – after handing two red poppies to the Archduke Ferdinand and his wife, the Duchess of Hohenberg, he takes their picture, "assassinating" them as the flash goes off. Many of the heads of state enjoy good personal relations and are reluctant to go to war: a tearful Emperor Franz Josef declares war on Serbia after being deceived by his Foreign Minister, and Czar Nicholas II and Kaiser Wilhelm II are shown as unable to overrule their countries' military mobilisation schedules. The German invasion of Belgium leaves Sir Edward Grey little choice but to get involved. Italy reneges on its alliance with the Central Powers (it joined the Allies in 1915) but Turkey joins them instead.
