Guy Martin, the motorcycle racer turned engineering enthusiast, sets aside the famous beach landings to focus on the airborne assault that opened D-Day. He traces the experience of the paratroopers who dropped into Normandy in the dark hours before dawn, tasked with securing bridges, crossroads and gun positions ahead of the seaborne troops. The film mixes archival footage and expert interviews with Martin's own hands-on approach, letting him handle the gear, aircraft and equipment those men jumped with, from parachutes to the gliders that followed behind. Historians walk through the planning, the scattered drops caused by flak and poor visibility, and the improvised fighting that followed when units landed miles from their objectives. Rather than retelling the beach story everyone knows, it makes the case that the paratroopers' chaotic, isolated firefights in the hedgerows were just as decisive to the invasion's success as the landings themselves.
