This documentary follows American senator Jim Webb on a 2,000 year journey from Hadrain's Wall through the time of the Border Reivers, the Plantation of Ulster and the emigration of hundreds of thousands of Scotch-Irish settlers to north America.
These plucky, hardened people made American society what it is today and their unique values and beliefs came the mainstream US identity. Rugged individualism, clanship, generosity, suspicion of authority and a willingness to die for their believes are some of the recognisable traits of an Ulster Scot.
They took on - and held their own - against the might of the Roman Empire, the medieval English, the Irish savages of northern Ireland, the Indian tribes of the American frontier and were the driving force behind the Revolutionary War and US independence.
While many in America refer to their ethnicity as Irish-American, Italian-American, etc most of the Scotch-Irish community refer to themselves as simply 'American' with no need to hyphenate.
