Watch on Soap2day. This documentary is set against the scenic backdrop of Mount Errigal in County Donegal. The mountains of Donegal are depicted like fairytale characters, where the hero Mount Errigal competes with neighbouring villain Mount Muckish. A fantastical narrative explains that the landscape is ‘a battleground where the weapons are the elements themselves’. Dramatic footage of storms and lightning blends with a superb score by Irish composer Brian Boydell.
