Vikings is ready to set sail once more.

‘Vikings’ Season 4 Premiere: First Sneak Peek At Rollo’s Wedding Night! Who Will Pull A Knife?

The History drama left fans biting their nails following Ragnar’s brush with his mortality in “The Dead,” and when the King returns next week in “A Good Treason,” he will be moments away from entering Valhala. Luckily for us, it appears the afterlife isn’t quite ready to welcome Ragnar to its ranks.

“Entry to Valhalla eludes Ragnar but as he lies near death in Kattegat events unfold beyond his control,” the History Channel teased. “Bjorn orders the arrest of Floki for Athelstan’s murder while in Paris, Rollo betrays the last of his Viking supporters to strengthen his position in the French Court. Meanwhile, in Hedeby, Kalf announces joint Earldom with Lagertha, but is power-sharing Kalf’s true intention and is Lagertha actually willing to share what once was hers?”
