Joe visits the towns of Ballywalter and Ballyhalbert on the northern shore of the Ards Peninsula in County Down. He stands at Burr Point, the most easterly point in Ireland, looking out towards Burial Island.

Joe takes a trip out of Ballyhalbert harbour in a small boat with Ernest Dunbar who tells him stories of historical shipwrecks. On the rocky seashore, Ian Wilson recounts a daring rescue of the large sailing ship, the Wild Deer, and laments the disconnect in modern life from shipping as sea trade has largely moved to larger ports on reclaimed land in the bigger cities. Back out at sea, Ernest shows Joe how he brings in catches of lobsters and prawns.

Professor Valerie Holt then shows Joe a reindeer antler and part of an antler from a great Irish deer, both of which were found on the shore and date to when the sea was much further out at the end of the last Ice Age.

Moving to Ballywalter, Joe tells of the area's involvement with the 1798 United Irishmen Rebellion and then speaks to Jim Fullerton who tells of his career in the merchant navy and captaining the Liverpool ferry. May McAdam invites Joe to her farm and talks of being in the Young Farmers' Association for 67 years.

Joe visits the graves of three Polish airmen from World War II at St Joeseph's church in Ballyoran and of five Commonwealth airmen at St Andrew's in Ballyhalbert. All were killed in accidents at the Ballyhalbert airfield. He discusses the graves with Reverend John Hemphill. Helena McCormick remembers the building of the airfield during the war and the arrival of child evacuees from Belfast. Jim Palmer walks around the derelict remains of the airfield outbuildings talking of his sadness that they have been allowed to decline.

Lesser Spotted Ulster is a long-running and popular programme that visits the places many of us have heard of but never been to. Presenter Joe Mahon gently explores what makes a place what it is.
