Vikings: Valhalla

Plotting to avenge a massacre in England, Viking armies converge in Kattegat — but 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.

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. Kåre revisits the holy site of a childhood trauma.

Olaf makes a pact with Kåre as Kattegat prepares for its defense. In Canute's absence, his father, Sweyn Forkbeard, shares England's throne with Edmund.

Olaf and Kåre gather their forces to invade Kattegat. Palace intrigue over control of England's throne results in an unexpected turn of events.
