In this episode, Martha travels north, taking in the extraordinary beauty of Dunluce Castle, and onwards to Mussenden Temple - only a romantic would expect to find a house here and only a lunatic would build it. She marvels at how Belfast was shaped by the Victorians, and visits Kearney Point on the Ards Peninsula to find out what's in a name. And she journeys south to Dunmoe, overlooking the site of the Battle of the Boyne.

In her final journey, Martha hits the spiritual trail, starting with the Blasket Islands off the coast of Kerry. In the Dingle Peninsula, Du Noyer discovered clochans - stone beehive huts. Martha heads north on a spiritual trail, taking in the islands of the Fermanagh Lakelands - White Island, Boa Island and the renowned Station Island.
