By early 1945 the last natural barrier standing between the Allies and the German heartland was the Rhine, and this film covers the campaign built to cross it. It opens in the Reichswald Forest, where Operation Veritable bogs down into a freezing, waterlogged fight through flooded fields and minefields. From there it moves to Operation Plunder, Montgomery's set-piece river crossing backed by a massive artillery barrage, and then to Operation Varsity, the airborne assault that dropped thousands of paratroopers and gliders in a single day, still cited as the largest one-day airborne operation ever mounted. Veteran testimony is woven through the archival footage, giving firsthand accounts of the Siegfried Line's defenses and the cost of breaking them. The film treats the Rhine crossing not as a single dramatic moment but as three linked operations, each with its own logistics and casualties, that together opened the road into the German interior and effectively ended organized resistance west of Berlin.
