Vikings: Valhalla

Plotting to avenge a massacre in England, Viking armies converge in Kattegat. However, siblings Leif and Freydis exact a different kind of retribution.

To save the life of Freydis, Leif agrees to join Canute and Harald's siege of London. Queen Emma dispatches stepson Edmund to secure an ally's help.

On a pilgrimage, Freydis and her party are savagely attacked. Harald and Leif seek a route through the marshes near London as Edmund is crowned king.

Leif proposes an audacious assault on London, one that Emma and Godwin fear their brash and headstrong boy-king, Edmund, will be too reckless to defeat.

Schemes, betrayals and politics rule the day as a new monarch takes the throne of England. Leif is hailed as a hero but secretly questions his faith.

Freydis returns to Kattegat and joins a sacred order, Canute solidifies his power in England, and Kåre revisits the holy site of a childhood trauma.
