Vikings: Season 4 Volume 1

Vikings returns for a gripping fourth season. Season 3 culminated with the extraordinary battle in Paris, where Ragnar (Travis Fimmel) seized victory from the jaws of defeat–but still returns to Kattegat dangerously ill. Thoughts of his death galvanize the forces who seek to succeed him as king, including his wife Queen Aslaug (Alyssa Sutherland) and his oldest son, Bjorn (Alexander Ludwig). Meanwhile, Lagertha (Katheryn Winnick) continues power struggles with her calculating, former second in command, Kalf (Ben Robson); Rollo (Clive Standen) betrays his Vikings heritage by remaining in Frankia and Floki (Gustaf Skarsgård) is seized for his brutal actions to the Christian priest Athelstan.
 
Joining the stellar cast this season is Peter Franzén as King Harold Finehair, a complex character who seeks to be King of Norway and a potential threat to Ragnar; Jasper Pääkkönen as Halfdan The Black, King Harold’s violent younger brother; and Dianne Doan as Yidu a completely different character within the world of the Vikings who fascinates Ragnar.
