In the last programme of the series Francis focuses his attention on the Anglo-Saxon invasion. Sheep-farming archaeologist, Francis Pryor, presents a brand new historical series which explores Britain A.D, the British national character and the ultimate British icon King Arthur. Finding new and previously unexplained evidence, Francis Pryor overturns the idea that Britain reverted to a state of anarchy and disorder after the Romans left in 410 AD. Instead of doom and gloom Francis discovers a continuous culture that assimilated influences from as far a field as the Middle East and Constantinople. Through scrutinising the myth of King Arthur to find out what was really going on when the Romans left, Francis is confronted by evidence that confounds traditional views of the 'Dark Ages'. There was also no invasion of bloodthirsty Anglo Saxons, rampaging across the countryside. With new archaeological evidence Francis discovers a far more interesting story.
