Actor Ardal O'Hanlon retraces his routes on a journey which looks at his connections to an Irish rebel and a colourful character in New York. The O'Hanlon name has been at the heart of many an Irish rebellion, and Ardal is desperate to separate the myth from the reality. He re-traces his Grandfather's exploits, from the morning of Bloody Sunday through to a dramatic prison-break; he also sets out to prove his connection to famous castle and an infamous 17th century rebel. But ultimately, it's a childhood myth which turns out to be true that takes Ardal to New York, where he uncovers the story of an extraordinary Irish dynasty at the heart of a modern American revolution. And from generations of bloody rebellion sprung the man who played Father Dougal McGuire... and George Sunday from My Hero.
