Vic the Viking (2013)

Fat Flaxe is flattened by stomachache and druid Urobe can't cure him, so the ship brings him to his old mentor's island. They are received by an impostor, who convinces Halvar a cure can only be made from seaweed from another island. While the men gather that, he overpowers the skeleton crew, including Wickie, who must hastily prevent the ship from being stolen.
