In Hispania, Rome seeks revenge on the barbarians who fought alongside Hannibal in his failed campaign to end the Republic. Governor Galba almost annihilated the Lusitanians, a Celtic tribe from the west of the Iberian Peninsula. The survivors, who live as refugees in their own land, unite around the former pastor and leader Viriato and organize a resistance guerrilla against the Roman occupation. The barbarians take advantage of their knowledge of the terrain to continue the fight, while Vetilio launches a large-scale operation with the aim of hunting down the elusive rebel leader. The two sides meet in the Tribola forest for a fatal clash.
