In 52 B.C., the Chieftain of the Arveni tribe, Vercingetorix, united the Gauls in a major revolt against the power of the Romans. This is his story, beginning with his rise to power. In one of the tribes, he rescues the 11-year-old Taranis, the only son of a Gallic hero who was executed by the Romans. Taranis follows Vercingetorix as he raises his army to fight for the freedom of Gaul.
