The long-running historical action drama returns with a string of new episodes to complete its sixth and final season. The first of two back-to-back episodes, "King of Kings," opens in Iceland, where Ubbe (Jordan Patrick Smith) faces a difficult decision after learning the truth about Kjetill (Adam Copeland). In Norway, Bjorn (Alexander Ludwig) tries to reverse the odds he faces in the battle against the Rus. Then, in "All Change," Oleg (Danila Kozlovskiy) isolates Ivar (Alex Hogh Andersen) after the Rus army returns to Kiev.
