Introducing the extraordinarily complex and violent world of the Norsemen, HISTORY’s® first scripted series races the gripping sagas of historical hero Ragnar Lothbrok. As claimed direct descendent of Odin, god of war and warriors, Lothbrok's mystical nature and devotion to the gods feeds his stealthy maneuvers and determination to become King of the Vikings.
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. Ragnar has been working in secret on a project that will turn the Viking world on its head. But first Ragnar must convince the leader of his community, the powerful Earl Haraldson, who is none too happy to share in the renown that this journey could bring to Ragnar if it's successful.
The stage is set for the first journey west by Ragnar Lothbrok as he gathers a crew willing to risk their lives to travel into the unknown. Earl Haraldson's paranoia reaches new heights as it becomes apparent that trust is hard to come by in this dark era.
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. Unable to ignore the riches this unsanctioned journey has returned, Earl Haraldson has no choice but to agree to let these warriors undertake a second trip out. The West has now been opened for the taking by Ragnar Lothbrok, and the world of the Vikings will never be the same.
The Vikings head back to England to see what other treasures this new world has to offer. Ragnar and his crew sail out with Earl Haraldson's permission… and also with Earl Haraldson's spy. After bloodshed on the beach, the Vikings choose the Sabbath to invade the town of Hexam and unleash a flood of violence and panic. In the midst of the terror, Ragnar and Lagertha discover that there are consequences for every action and Earl Haraldson is always watching.
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?

He must now choose the path that will lead him back to his freedom.
Ragnar, weak and still hurt, must meet the Earl head-on after it comes to light that Rollo has been tortured on Haraldson’s orders. The two men will come together face to face with a single outcome possible: Only one man will leave this fight alive.

As the Vikings come together to sacrifice and give thanks to their gods, Athelstan discovers just how strong his Christian faith still is.
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.
