In August 1944, as Allied forces push east from Normandy, a British battalion encounters fierce German resistance while trying to cross the Seine River. With bridges destroyed and no tank support in sight, they must fight to secure a critical bridgehead and continue their advance. On a ridge above the river, a single major's actions may determine whether their position holds or collapses under a German counterattack.

During Operation Market Garden, paratroopers of the 82nd Airborne race to seize the vital bridges at Nijmegen. As savage street fighting erupts, German counterattacks close-in on lightly defended landing zones—putting inbound gliders, vital reinforcements and the entire Allied plan at risk.
