Plot: The Roman Empire is stretched across many nations, including Britain. In their conquest for more land, the Romans went into Sarmatia where they fought the very brave Sarmatian cavalery. The Romans, impressed by the Sarmatian's weaponery and fighting skills, included them into their army as knights. After 15 years of serving and fighting for the Roman Empire the Sarmatian Knights, lead by Arthur/Artorious Castus, are about to receive their freedom as the Romans are leaving Britain. But the Knights must carry out one final order before they are free. A Roman priest and his family, especially his son Alecto, must be rescued from the invading Saxons. But there is another danger lurking on the road to freedom - the Woads, British rebels who hate the Romans.
