family’s cows, which escaped during a violent thunderstorm. Pursuing the cows they accidently chase the chieftain’s sheep away. The Viking chieftain, Gorm, demands compensation for his lost sheep. The children, therefore, have to go with their father, Svend, to the market in Ribe to sell their products: oxhides, amber, chickens and ducks - in order to get enough money for Gorm.

His son, Arne, therefore, will have to go with the chieftain as his slave.
