Meanwhile, the nephew of Vitalstatistix, Justforkix, is sent from Parisium to the Gaulish village to become a man and Asterix and Obelix are assigned to train the youngster. The stupid son of Cryptograf, Olaf, listens to a conversation of the coward Justforkix with Asterix and Obelix and kidnaps him. While returning to the Viking village, Justforkix meets Abba, the daughter of Timandahaf, and they fall in love for each other. But the Machiavellian and ambitious Cryptograf plan to marry his son Olaf with Abba and become powerful.

See how the Vikings really learn the meaning of FEAR, in the end!
