This massively ambitious series, comprised of sixty five-minute programs, traced the history of Ulster’s connections with Scotland from ancient times to the present day. It focused on the territories’ shared Celtic origins, and how immigration between the two territories helped forge two shared yet fundamentally different cultures. The program also looked at how emigration from the two territories helped nourish other cultures in England, Wales, and Scotland as well as North America.

Told with a single narrator, with the voices of several (uncredited) actors providing the voices of different historical figures, A Narrow Sea provided a kaleidoscopic picture of two cultures, and the social, political, and sociological forces that shaped them.
