One little ancient British village still holds out against the Roman invaders. Asterix and Obelix are invited to help. They must face fog, rain, warm beer and boiled boar with mint sauce, but they soon have Governor Encyclopaedius Britannicus's Romans declining and falling. Until a wild race for a barrel of magic potion lands them in the drink.
Due to an unfortunate accident involving Obelix throwing a menhir, Getafix the druid not only loses his memory, but goes completely mad. Now deprived of the wisdom of their beloved druid and the protection provided by his magic potion, the Armorican village falls prey to a proclaimed soothsayer who comes with ominous predictions and overweening ambitions. It's up to Asterix to keep his villager friends within reason and hopefully get Getafix to remember the magic potion's recipe before the impending Roman attack.
