Broadcaster Diarmuid Gavin travels to the heart of Africa and beyond in a quest to find the very origins of the Irish people. Who are the Irish and whose blood flows in our veins? A landmark series for RTÉ, Blood of the Irish explores the most fundamental questions about the Irish population; who were the first people to settle here and where did they come from? Why are the oldest Irish human remains less than 10,000 years old when just 100 kms away in Britain, human traces go back 700,000 years? Did the first Irish arrive overland on an ice bridge, or on a small fragile boat blown ashore by the winds of chance?

Produced by Crossing the Line Films, a veteran production company skilled at documentaries exploring history, science and adventure, the documentary is full of spectacular landscapes, cutting edge DNA studies, computer graphics, latest archaeology and prominent academic contributors. It also includes ordinary Irish people and their own quest for their origins – including even an appearance by Daniel O'Donnell.

For all those with an interest in Irish history and prehistory, geneaology, genetics, archaeology and general Irish studies, 'Blood of the Irish' is a showpiece documentary which offers an educational and approachable view into one of the great mysteries of Irish people. Who are we; and where do we come from?
