The first episode of a thirteen-part series traces the chain of decisions and grievances that carried Europe from the armistice of 1918 to the outbreak of war in 1939. The film argues that the peace settlement itself, not just Hitler's rise, planted the triggers for the next conflict, walking through the punitive terms imposed on Germany, the economic collapse that followed, and the political vacuum that let extremism take hold. Archival photographs and newsreel footage of Versailles, Weimar-era Berlin, and the march toward rearmament anchor the narration, which moves briskly through the interwar years rather than lingering on any single event. The series positions this episode as the foundation for the rest of its run, framing the Second World War less as a sudden eruption than as an outcome built into the terms of the first war's ending. It suits viewers who want the causal chain laid out plainly before the later episodes get into the war itself.
