All the episodes from the third season 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. In this season, King Alfred (David Dawson) dreams of uniting the kingdoms of England, but his plan runs into trouble after the Danes attack and he is left with no choice but to seek assistance from warrior Uhtred.
