The hero, named Horn, is the son of the king Aälof of Suddene (probably somewhere near Devon). Horn is orphaned after the Saracens kill his parents. He and twelve companions then set sail in a boat only to end up on the shores of Brittany, where he grows to manhood and falls in love with the king's daughter Rigmel. There he defends the kingdom from invading Saracens, but the king banishes him to Ireland after he is wrongfully accused of trying to usurp the throne. In Ireland, Horn again proves his heroism and is offered the hand of the king's daughter. Horn refuses it and after some time returns to Brittany to rescue and marry Rigmel.
