PARIS, THE VIKING SIEGE

841: A fleet of longships enters the mouth of the Seine. For the first time, Vikings venture into the heart of the Frankish kingdom, but the king is not concerned: the major cities lie far from the coasts, and Paris, set deep inland, seems out of reach. An illusion... For from the North, the Vikings grow bolder.

Led by the formidable Ragnar Lodbrok, hordes of warriors push ever deeper into the heart of France, plundering the land - and even seeking to settle there permanently.

How did they outmaneuver its defense systems and impose their power at the core of French territories? How did they conquer Normandy and turn it into one of the most powerful duchies in Europe?

For a long time, the history of the Vikings in France remained fragmentary, but in recent years, archaeological excavations and scientific studies have shed new light on this great conquest. In light of these unprecedented discoveries, and supported by AI-driven cinematic reconstructions, this documentary aims to recount the incredible epic of the Vikings in the heart of the Frankish kingdom.
