Restored Allied combat film anchors this account of the United States Army Air Forces in World War II, tracking the campaign from Italy through the invasion of France. The film follows Operation Strangle, the sustained effort to choke German supply lines in Italy by hitting roads, rail yards, and bridges from the air, and connects it to the broader push to clear German fighters from the skies ahead of D-Day. It spends real time on the bombing of Hitler's synthetic oil refineries, framing fuel denial as the campaign that finally broke the Luftwaffe's ability to contest the air. Cockpit and ground footage, formation shots, and bomb-run sequences carry much of the narrative, with narration filling in strategy and cost. The emphasis throughout is on scale and casualties, the crews lost over Ploesti and the Reich's refineries, and how those losses translated into the air superiority that let the Normandy landings happen at all. It plays as a focused campaign history rather than a general overview of the air war.
