In April 1945, most of Germany is occupied by invading Allied forces. As the Soviets near Hitler's hiding places, the Nazi regime starts to disintegrate.

In the winter of 1944, Germany is losing the war on all fronts, but Hitler refuses to contemplate surrender. Instead, he calls leading military generals to a secret location and orders them to start preparing a massive surprise attack against the Western Allies as part of his policy of total war. It's an attack he believes will finally break them.

At the end of March 1945, Nazi Germany is on the brink of collapse, and with Berlin under daily bombardment, Hitler has permanently retreated to his bunker.
