The vikings launch their attack on Paris. Lagertha and Kalf lead the attack on the bridge and the main gate. After their attempt to knock down the gates with a battering ram is unsuccessful, they manage to pull them down - but are not prepared for what they find on the other side. Floki leads the attack on the wall but the city's defenses are formidable. As it becomes clear the battle is lost, Floki cannot understand why the gods have deserted him. In Kattegat, Porunn leaves her child with Auslag and goes off into the wilderness.
