The Queen Cleopatra bets against the Roman Emperor, Julius Caesar, her people continue to be great, even when the times of the Pharaohs has passed. She yells (against all logic) to build a new palace for Caesar in just three weeks. Since her architects are busy differently or conservative in style, this honour falls to Edifis. He is always to construct the palace and also be covered in gold or, if not, his fate will be to be eaten by crocodiles. Edifis calls upon an old friend to help him out: The magnificent Druid Getafix from Gaul, who devotes a fantastic potion that gives unnatural power. Safeguard and in order to help the old Druid, Obelix and Asterix accompany him to his journey to Egypt. When Julius Caesar gets wind of the project succeeding, he has the building site. But like the pirates, '' he has not relied on Obelix and Asterix.
