Julius Caesar (John Gottfried John of Govred) fought north and south with his powerful army, but he was withered in a tribe inhabited by Gauls. It turned out that Palo Lamy (Claude Pi é plu), a wizard in the tribe, invented a potion that could teach people to have great power in just one drop, while Abelis (Kristen Clavier Christian Clavier) fell into the potion in an accident. So it has endless strange power. Abelis protected the tribe with his special powers, which made the possessive Caesar very angry. He slapped General Dlitos (Roberto Benigni Roberto Benigni) and ordered him to lead troops to attack the tribe. However, Delitos had a rebellious heart for a long time. He not only put Caesar under house arrest, but also kidnapped Palo Lamy and wanted to use his potion to realize his ambition to conquer the world.
