In 376 AD, thousands of Gothic warriors arrived on the banks of the Danube, pleading for refuge from the Roman Empire. They weren't there to conquer; they were fleeing something no Roman could yet name: a people who had emerged from the depths of the Central Asian steppes and who would forever change the course of civilization. The Huns stormed into the ancient world like an unprecedented tempest, and their arrival marked the beginning of the end for the order Rome had maintained for centuries.

This documentary traces the complete history of the Hunnic people: their possible origins in the Mongolian steppes, their nomadic way of life, their mastery of the composite bow and mounted warfare, and their rise from an unknown tribe to an empire capable of challenging the power of both halves of the Roman world. At the heart of this story is Attila, the leader who unified the clans and built a power that stretched from the plains of Hungary to the borders of Persia, a man whom European tradition would remember as the Scourge of God.

We explore the great campaigns against Constantinople and the Eastern Roman Empire, the invasion of Gaul and the Battle of the Catalaunian Plains, the march on Italy and the mysterious encounter with Pope Leo, as well as the empire's sudden end and the enigma left behind by the Huns. A story of horsemen, ambassadors, tributes in gold, and decisions that shaped the fate of Europe, told from ancient sources and the findings of modern research.
