In 8th century Scandinavia, Ragnar Lothbrok is a warrior and a farmer who dreams of finding riches by bucking the tradition of raiding to the east.

A monastery in Lindesfarne is about to get a firsthand look at how the Vikings operate. In and out in a flurry of violence and terror, Ragnar and his crew raid the monastery for everything it contains, from treasure to monks who can be sold as slaves.

In the Great Hall of Kattegat, a seer reads Earl Haraldson’s future and tells him that Ragnar Lothbrok searches for his death. The unanswerable question is whom do the gods favor more?

At the behest of King Horik, Ragnar assembles a small party to travel to Gotaland (modern day Sweden) to resolve a land dispute with the area’s leader, Jarl Borg.

The appearance of the Viking fleet causes panic among the population of Paris. The Emperor Charles, urged by his daughter Gisla, announces in Court he will remain in the city. The defense of Paris is in the hands of its Commander, Count Odo, who hopes that a heroic victory against the Vikings will gain him Gisla’s hand in marriage. The Vikings establish camp downriver from the city and plan their attack.
Entry to Valhalla eludes Ragnar, but as he lies in his sick bed in Kattegat events unfold beyond his control. 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. 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?
In England, King Ecbert's true ambitions are revealed as he plans to gain the crown of Mercia. While outside Paris, the Vikings attack with considerable force, but can they overcome Rollo's defenses? Meanwhile, Harbard, the mysterious wanderer, returns and causes a stir amongst the women of Kattegat.
Defeat for the Vikings calls Ragnar's leadership into question as they evacuate their camp and move back down river. Ragnar remains inscrutable until he orders the fleet to beach at a cliff face and unveils an ingenious plan. Rollo and Gisla have news that strengthens Rollo's position at the French Court whilst Count Odo fails to identify his true enemies, with fatal consequences.
The labors of the Vikings eventually bear fruit as, within sight of Paris, they re-launch their boats but this time along with some interesting structures that Floki has built. Aethelwulf and Alfred eventually arrive in Rome and honors are conferred by Pope Leo but relations are not so cordial in Wessex between King Ecbert and the disgruntled King Aelle.
A recap of Season 1 through 4.
Ragnar's reappearance in Kattegat triggers a chain of events no one - except the Seer - could have ever imagined. He unexpectedly arrives home to see what has become of his sons and to handle unfinished business in Wessex with King Ecbert. Meanwhile, Lagertha plans a power play in Kattegat and Bjorn prepares to fulfill his long-held dream to explore the Mediterranean in a sleek new boat built for him by Floki.
The Kattegat locals chide Ragnar that the gods have deserted him as he struggles to crew his voyage to Wessex. It's Bjorn who has charisma now as he prepares to fulfill his long-held dream to explore the Mediterranean in a sleek new boat built for him by Floki. By contrast, Ragnar must accept weathered boats and a crew he has bribed but when Aslaug foresees that the fleet will be lost in a vicious storm her warnings go un-heeded by Ragnar and her precious son, Ivar.
Ragnar's fleet is shipwrecked and washes up on the Wessex coast, but without enough survivors to form a credible force, Ragnar and Ivar have a difficult decision to make.
