While hunting in the woods, Ragnar overhears screams and finds his farm is under attack of Earl Haraldson and his men that kills people, livestock and his entire farm. Ragnar is wounded and asks his family to flee to their boat. He surrenders to Haraldson to buy time for his family reach the boat but he lures and flee from Haraldson an his men, jumping off a cliff to the river. Athelstan jumps in the water and rescues Ragnar. Then they take him to Floki's home that shelters the family and heals Ragnar. Meanwhile Haraldson tortures Rollo to know Ragnar's whereabouts and arranges the marriage of his daughter with an old Earl to be more powerful against the will of Siggy and their daughter.
"Raid" is a great episode of "Vikings" where Haraldson is the central character with his cruel attitudes towards Ragnar, Rollo and his own daughter. What Ragnar and Rollo will do is unknown but maybe Haraldson has signed his death sentence with his attitude. Let's see the next episode to learn his fate after the challenge of Ragnar. My vote is eight.
Title (Brazil): "Raid"
