When he is out hunting, his farmhand tries to rape Astrid. He is chased off the farm by the women. When Arne learns what has happened, he is driven to the Faalsund inn, trembling with rage, where he almost kills Erik, the farmhand.

At first he manages to fend off the wolves with a wooden club, but then one of the beasts knocks him to the ground and the others are all over him...
