The battle for supremacy begins as the ancient world splits into two: Roman vs. Barbarian. Hannibal of Carthage builds the first great alliance to defeat Rome before it becomes an unstoppable machine. The general launched a bold and unprecedented campaign to strike at the heart of the Republic: he conquered the Alps and entered Italy in the direction of the capital, leaving a trail of destruction in his wake. But, although Hannibal wins the battles, at the same time he is losing the war. Rome, with no adversary to stop its advance, traverses barbarian territory by plundering it and executing bloody revenge against the tribes who were fighting alongside Hannibal. Thus emerges the first wave of resistance in a 700-year fight for freedom. 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.
