Nothing can stop this Viking fleet - except the battle of two brothers for leadership.
The longboat fleet of the Viking leader Grimr Skullsplitter is located on the Rhine in the middle of the Frankish empire, when he dies of his wounds after a battle.
It is clear to his son Olav that he will now take over the leadership of the fleet. But his brother Thorbrand also seizes power. Suddenly the Northmen are divided into two camps and cannot agree on a common course of action while an army of the Franks approaches. What began as a profitable adventure ends in a massive battle. He brings glory to one, death to the other.
