This episode of McGilloway's Way features Derry City in Co. Londonderry, Letterkenny, Bogey and Fanad Head all in County Donegal. The footage begins in Derry City with scenic shots of a fresh water lake and all the flora and fauna which surround it. The presenter makes the point that normally, when discussion concerns the intersection between transportation routes and the natural world, it tends to be focussed on the detrimental effect that the former can have on the latter. However, in this case, the railway embankment ended up being a good thing, as it has created a 'marvellous' safe habitat for the wildlife.
Next, the viewer is brought to Letterkenny, where a blacksmithing festival is taking place. McGilloway introduces Mike Crummie, a blacksmith from the highlands of Scotland who has travelled over for the event. Here, Crummie explains that the blacksmith's craft has been split into four different sections. The first is the farrier who makes and looks after horse shoes, the next is the artist blacksmiths, who specialise in the decorative aspects of the craft, following this is the agricultural blacksmith and, lastly, is the general blacksmith, who has broad knowledge across all the sections.
Badgers are on the agenda next, with local man David Agnew showing McGilloway the best places for sightings, followed by a discussion of a badger's behaviour in their natural environment.
To finish the programme, Audrey Whittaker, explains the process of taking natural wool and spinning it into yarn, before then dying it using a time-tested technique of boiling lichen, which can be found on the rocks by the ocean.
