The untold story of the Roman invasion of Northern Britain. This film brings to life one of most extraordinary conflicts in British history.  This incredible story throws a light into the sheer tenacity of the British Northern Tribes and their determination to hold back the mighty Roman army from conquering their lands. Nearly 2000 years ago most of Britain was a settled peaceful province of the Roman Empire. But the north held out against what was then the world\'s only superpower and insurrection flared across Hadrian\'s Wall. In 208AD, the Roman Emperor Septimius Severus marched into Scotland with 40,000 men – one of the largest invasion armies Rome ever mobilised. Severus had been a hard-nosed general who had seized his opportunity and fought his way to become Emperor. He was both ambitious and devious, and a man driven by power at any cost.
