Julius Caesar has conquered almost all of Hispania, except for one small Iberian settlement. This settlement bears many similarities to that famous Gallic village we know so well. In his quest for complete domination, the Roman leader has the village chief's child kidnapped. Pepe, the young and proud son, is transported to Gaul. There, he and his captors come into contact with Asterix and Obelix. From that moment on, the Romans are unable to carry out their plans and lose control.
