All the episodes from the first two seasons of the historical BBC drama centred around the wars between the Saxons and Danes during the ninth century. Alexander Dreymon stars as the warrior Uhtred of Bebbanburg, the son of a Saxon nobleman who was captured by the Danes as a child and raised as one of their own. After Uhtred is blamed for an English uprising he is imprisoned along with fellow captive Brida (Emily Cox). When they are released the pair flee to Winchester, the capital of Wessex, and pledge allegiance to King Alfred (David Dawson). Vowing to avenge the death of Earl Ragnar (Tobias Santelmann) and recapture his ancestral lands of Bebbanburg, Uhtred then travels north as King Alfred begins looking for a Christian Dane capable of succeeding him and uniting the kingdoms of England.
