When Ragnar returns home from Wessex, he learns that Siggy died saving his two healthy kid sons. Lagertha expects help to depose usurper Kalf from 'her' earldom Hedeby, but Ragnar refuses to waste any manpower now he has set his mind to raiding Paris, which Athelstan keeps describing as a pillager's wet dream. While Bjorn still can't connect with his bride, Rollo is promised a surprisingly bright future. In Wessex, crown prince Aethelwulf gets his pregnant wife Judith to admit her adultery with Athelstan and gathers a group of nobles to avenge the insult by bloodily exterminating the Viking settlement. King Ecbert arrests the 'rebellious' nobles, but secretly congratulates his son for helping to eliminate two threats to their dynasty.—KGF Vissers

While returning to Kattegat, Ragnar asks Athelstan how Paris is. Floki hates the Christians and Athelstan. When they arrive, Torstein's widows learn that he is dead and Rollo that Siggy died. He blames himself for treating her badly and becomes drunken and self-destructive. Bjorn beats Rollo that is risking to be murdered. Ragnar presses Auslag to know why she was not with their children. In the end she tells about Harbard while Helga tel what happened to Kloki that believes he is Odin. Lagherta learns that Kalf has self-proclaimed Earl. Judith tells Aethelwulf that she is pregnant and he knows that he can not be the father. King Ecbert summons his son to hear a man from the Nordic settlement that explains that a farm was burnt by Christians and Ecbert asks his son to end with the conflict. What will Aethelwulf do? Meanwhile Ragnar informs that they will attack Paris.—Claudio Carvalho, Rio de Janeiro, Brazil

The Vikings return to Kattegat, and the women learn of Torstein's death as the men learn of Siggy's. Ragnar is suspicious about why Aslaug was not watching the children.

Ever since hearing about Paris from Ecbert, Ragnar has become obsessed with the city. Athelstan says that the city of Paris is protected by huge ramparts that run for miles. Inside the city are buildings made of marble and stones. He also adds that the women of Paris are beautiful beyond comparison.

Floki becomes more outspoken about his hatred for Christians, and Athelstan. He does not like Ragnar speaking to Athelstan and believes that Athelstan is conspiring to convert Ragnar to Christianity. Helga tells Floki about Harbard, and he claims that Harbard is a god. Floki learns that Harbard slept with Aslaug after seducing her. It was because of Harbard that Aslaug was not looking after the children.

Bjorn goes berserk when the soldiers make fun of him for being sad over Porunn's scars. They say that everyone has lost someone in their family, and Bjorn has simply not come to terms with his sorrows. When Bjorn fights, he gets thrown out of the tavern. Bjorn and Rollo come to blows as Rollo feels that Bjorn is being disrespectful towards Siggy's death. Rollo takes a heavy beating from Bjorn and has to walk away.

Aethelwulf learns that Judith is pregnant with Athelstan's child (as she and Aethelwulf had not slept together since the birth of their first child). Ecbert gets reports that the Viking settlement is being attacked by the English farmers. Ecbert asks Aethelwulf to lead a large force to the settlement and to provide his protection to the settlers.

A messenger arrives in Kattegat to tell Lagertha that her earldom has been usurped by Kalf. She asks Ragnar to help win it back. Ragnar tries to argue that a civil war will only mean that more of their own people will die.

Instead, Ragnar meets the Seer to find out if he will conquer Paris. The Seer says that only the dead will conquer the city. Ragnar tells the men that they will raid Paris in the spring. Ragnar gets Athelstan to reveal to his court about the grandeur of Paris.

Ragnar goes with Lagertha to Hedeby to speak with Kalf, although he decides not to help fight for Lagertha, and instead asks him to join the raid on Paris. Since Ragnar refused to fight for her, Lagertha leaves Kattegat.

Rollo meets the Seer and reveals that he is very bitter at Ragnar as he represents everything that Rollo is not. Rollo was rejected by his parents, and by Lagertha, and Ragnar ended up getting everything, while Rollo could not even get Siggy. The Seer says that Rollo will jump with joy if he was told what the Gods had in store for him, and sends him away.

Aethelwulf leads his soldiers to the settlement and kills all the settlers.

Ragnar confronts Aslaug about Harbard, and she only says that Harbard is the person who cured his son. Floki tells Ragnar that Aslaug slept with Harbard and that Harbard is another name for Odin.

King Ecbert finds out about the settlers' fate; he chides his nobles and arrests them for treason, then in private reveals that it was his plan all along.
