All the episodes from the fourth 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, Lord Aelfric (Joseph Millson) loses half of his army of men in Bebbanburg after a Viking raid. When Uhtred hears of this news he sees an opportunity to attack Bebbanburg, though King Edward (Timothy Innes) refuses to help.
