Against the backdrop of rural Northern Ireland, An Irish Goodbye tells the story of estranged brothers Lorcan (James Martin) and Turlough (Seamus O’Hara) who reunite following the untimely death of their mother (Michelle Fairley).

Under the watchful eye of odd-ball parish priest Father O’Shea (Paddy Jenkins), the brothers’ pained reunion is worsened by the fact Turlough must now make new care arrangements for Lorcan, who has Down syndrome. A robust and dedicated farmer, Lorcan’s dreams of continuing to live and work on the family farm are thwarted when Turlough announces he’s sending him to live with their Aunt on the other side of Ireland.

But when the pair discover an unfulfilled bucket list belonging to their late mother, Lorcan senses an opportunity: he’ll only agree to leave the farm once he and Turlough have themselves completed every single wish on their mother’s list…

… all one-hundred of them.
