Infuriated by belittlements, Queen Cleopatra makes a deal with Julius Caesar. If the Egyptians built a palace at Alexandria in three months, which is larger than Caesar's palace in Rome, he must acknowledge that Egypt was the greatest of nations. To perform this task, Cleopatra hires the architect Numerobis, on pain of death and much to the dismay of Cleopatra's usual architect, Pyradonis (Amonbofis in French version). He and his secretary Papyris discuss the druid Getafix (Panoramix in the original French), whose potion empowers its drinkers, and Numerobis goes in search of him.
Numerobis arrives in Gaul and persuades Getafix to embark with him to Alexandria. Once they arrive, they find construction has started already with many workers. Pyradonis realizes he must stop Numerobis from finishing the palace within the deadline by sabotage. First he attempts to start a uprising among the workers and gains their support because their working hours are too long and they are whipped too often. Getafix cooks a new potion which gives everyone super strength, allowing them to dramatically increase the pace of construction. Pyradonis them gets the shipping company to throw the shipments of stone into the Nile. Obelix attempts to climb the Great Sphinx and breaks off its nose, using his super strength to lift the structure and place the broken nose under it, crushing it.
Later, after Pyradonis gets Asterix, Obelix and Getafix trapped in a pyramid, Obelix drinks three drops of the potion and breaks a path for them to escape. They still get lost but Idefix (the dog) sneaks in and shows them the way out. After framing them for the attempted assassination of Cleopatra, Pyradonis finally decides to inform Caesar about the potion's use and the potential victory of Cleopatra. Caesar knows the Gauls (having failed to capture their village multiple times) and decides to besiege the construction site using Trebuchets until Asterix, Obelix and Getafix surrender. Numerobis, Papyris and the three Gauls defend the site and decide to inform Cleopatra of Caesar's actions. Meanwhile, Pyradonis and Numerobis, after drinking the potion, fight in the site until Numerobis finally wins the duel. Cleopatra arrives on the battlefield and reprimands Caesar's lack of sportsmanship. The Romans are forced to stop the siege and assist in continuing the construction, which is finished on time. The palace is inaugurated, and Caesar willingly names Egypt the greatest Empire there ever was. Numerobis wins a large amount of gold, Getafix receives manuscripts from the Library of Alexandria; Cleopatra and Caesar fall in love. All the protagonists partake in a banquet (including some of the movie's Roman antagonists).
