Season 1

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

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.

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.
