Agrippa

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.
