After the latest bashing of the Roman legions by the Gauls, the Romans try to contain the threat from the Gaulish village by building a stockade around it, threatening to isolate the Gauls from the rest of the world. In response, Asterix and Obelix make a bet with them: the two Gauls will break out and claim their right as Gauls to travel freely all over their land, collecting the local delicacies and bringing them back to prove their point. Ham from Lutetia, fizzy wine from Durocortorum, fish stew from Massila in the south... soon their shopping bag is full.
