Abducted by a Viking warlord after his father is slain in battle, young Uhtred adopts the Norse way of life until tragedy befalls his new family.

Caught between his scheming uncle Ælfric and pitiless Viking warlord Ubba, Uhtred goes on the run and seeks out Alfred, the man who would be king.

Uhtred allies himself with newly crowned Alfred, but his commitment to the nascent king jeopardizes his bond with Brida.

King Alfred keeps Uhtred close with a tactical play, but Uhtred soon realizes he's been tricked. Meanwhile, a great battle looms over Wessex.

Uhtred leads a raiding party to Cornwall on a mission for wealth and independence and attracts the attention of a beautiful sorceress queen.

As a consequence of their actions in Cornwall, Uhtred and Leofric face off in a death match. The Danes launch an invasion of Wessex.

A united King Alfred and Uhtred leave the cover of the marshes and make a rallying call to all Saxon armies.
