A new centurion arrives at a Roman camp. He's Centurion Ignoramus. He plans to attack the Gauls from the village. Its Obelix's birthday, so they're letting him fight the Romans by himself. Some guy from Rome thinks he can corrupt the Gauls and make them weaker.
(The way the Roman speaks is basically making fun of Native Americans.)
His idea was to get the people in the village to make menhirs and all become so interested in making money they wouldn't devote any time to fighting. Things get out of hand not only in the village but in Rome itself.
The whole story is a take on the greed and lack of concern for people that is evidenced by many big businesses.
