If you thought Season 3 of “Vikings” couldn’t get any more intense following the shocking demise of Athelstan (George Blagden) -- think again! In the upcoming episode of the hit History Channel series titled “Paris,” our favorite pagans will finally attack the City of Lights. And you can bet their raid will cause the utmost destruction.

The synopsis for episode 7 suggests that the appearance of Ragnar (Travis Fimmel) and his Viking fleet with create chaos throughout Paris. However, Commander Count Odo, the man behind Paris’ defense tactics, will remain calm as he expresses his confidence “that the city is prepared” for battle against the dirt-covered foreigners.

“The Northmen have been scouting the countryside and our defenses. We must expect them to attack any day now,” Count Odo says to Emperor Charles (Lothaire Bluteau) in a clip from the forthcoming installment. But the French monarch seems to be concerned only about the safety of his daughter, Princess Gisla (Morgane Polanski), after he was unable to send her away in time before the siege.

“I did not want to be sent away. I wanted to stay here with you. There is nowhere I’d rather be than here in Paris beside you in your hour of need,” she says, adding that she’s spent much time with the people of Paris and knows they are “frightened to death” of the pagan army that has washed up on shore.

And they should be. Ragnar and the Lothbrok clan are determined to raid Paris -- and it looks like they’ll cut down anything or anyone who stands in their way. In a sneak peek clip from episode 7, viewers can watch as the Vikings plan a calculating -- and dare we say, bloody -- attack against the city while camping downriver from Paris.

Rollo (Clive Standen) suggests that after having a closer look at the city, he thinks it’s wise to attack from both the land and water. Lagertha (Katheryn Winnick) then volunteers to lead the raid at the gates of Paris, which is when Kalf (Ben Robson) interjects, adding that he’ll accompany her. Considering he just usurped her Earl ship, viewers can bet Lagertha won’t take too kindly to his companionship -- or input for that matter.
