June 22, 1941. At 4 a.m., Germany, without declaring war, unleashed the might of the most advanced military machine ever created on the Soviet Union. Documentary footage captures the first hours of the invasion: the Russian army puts up unprecedentedly daring resistance, the Nazi vultures are destroyed in the air, and Great Britain, only yesterday an adversary, becomes an ally.
             

In the Soviet Union, new, well-equipped divisions were being formed, ready to come to the aid of Moscow under attack by the Nazis. The enemy, on the other hand, was suffering heavy losses, but this did not stop Hitler, who set his sights on capturing and destroying Soviet cities. Germany's thirst for victory led to a crushing and shameful defeat.
