Bósi is a rough boy who is eventually outlawed for maiming some other folk in a ball-game. Herraud, discontented, gains permission from his father, over Sjód's objections, be allowed to set off on a Viking expedition with five ships. Herraud is eventually joined by the exiled Bósi and they successfully plunder for five years. Meanwhile, back in East Götaland, Herraud's half-brother Sjód extorts funds from Bósi's father Thvari under the pretence that this is legal compensation for those men whom Bósi has injured. Now it chances that Bósi's ship was driven to Wendland, where Sjód happens to be on a purchasing expedition for King Hring. Bósi and Sjód quarrel over the matter and Bósi kills Sjód.
