Julius Caesar devises a diabolical plan to conquer the rebellious Gauls who still dare to resist the Roman Empire. He will attempt to turn their small village into a degraded suburb, doomed to adapt or disappear. For this purpose, someone who has built many INSULAE, many of which did not collapse, is called upon - the architect Orthogonious. Thus, when the "Residence of the Gods" is finally built and inhabited, life in the small Gallic village begins to change. Money flows abundantly and the villagers' mentalities start to shift. Where weapons failed, could money succeed? Will the small village become alienated? Asterix is forced to use drastic measures to change this ominous situation. Somewhere, there is also a contract for some pyramids in the desert. Could it be a trap?
