Rob Penn travels the length and breadth of the Celtic fringe (from the wilds of Scotland, via Ireland, Wales, Cornwall and the Isle of Man to the heart of Brittany) on a quest to get to the bottom of his Celtic roots. Along the way, dressed in a kilt and clutching a blackthorn stick he endeavours (with mixed and hilarious results) to become a Celtic poet. His odyssey takes him from standing on the table in the corner of an Irish pub, struggling to be heard over the shouts of the drinkers, to the stage at Lorient in Brittany where he must perform his less-than-spectacular poetry in front of an audience of 40,000. He is aided and abetted on his journey by a cast of colourful characters, including a Cornish lady with a penchant for men in kilts, the winner of the Whitest Buttocks in the Isle of Man Competition and a crystal-clutching Californian.
