Abraracourcix, the village leader, learns from his brother that his nephew of Lutèce, Goudurix, must land in the village with the mission to make him a man (a real Gaul!). Asterix and Obelix are all designated to take care of this young city boy. At the same time, we meet the Normans, brave warriors of the far north... These barbarians are so brave that they do not know fear... But their leader, Grossebaf, would like to know her because it seems that she gives wings, and so that we can fly... That's how the Normans decide to go to other shores to "learn fear". And it happens that our Gauls are afraid of only one thing: that the sky falls on their heads. But Goudurix, he, is a champion of fear...
