Operation Carpetbagger was one of the most closely guarded American operations of the Second World War, a program that stripped down B-24 Liberator bombers and sent them low over occupied Europe at night to drop weapons, supplies, and agents to resistance fighters. This film follows the story through veterans who flew and crewed those aircraft, recalling the specific dangers of flak, flying blacked-out at treetop height, and locating drop zones marked only by resistance fighters' torches on the ground. Archival footage of the modified B-24Ds, briefing rooms, and airfields sits alongside interviews that lay out how the missions were planned and why the losses were so heavy. The film traces the operation's role in arming the French Resistance and other underground networks ahead of and after D-Day, showing how a mission built on secrecy and improvisation became a quiet but significant piece of the invasion of Europe. It is a crew's-eye account of a program most wartime histories mention only in passing.
