Britain entered the First World War with no conscription, yet by 1915 hundreds of thousands of young men had already queued outside recruiting offices. This film asks why, tracing the mix of patriotism, propaganda posters, and peer pressure that made enlistment feel less like a choice and more like an obligation. Historians walk through the recruiting drives, the white feather campaigns aimed at shaming men in civilian clothes, and the promises of adventure and comradeship that recruiters leaned on to fill the ranks. Archival photographs and period footage sit alongside expert interviews explaining how whole friendship groups and workplaces signed up together under the Pals Battalions scheme, ensuring that a single bad day at the front could devastate an entire town. The film follows some of these volunteers from the enthusiasm of 1914 into the trenches, where the war they imagined and the war they found rarely matched. It closes on the human cost of a rush to arms built on ignorance of what modern warfare would actually mean.
