Set against the backdrop of a working farm in rural Northern Ireland, 'An Irish Goodbye' is a black comedy following the reunion of estranged brothers Turlough (Seamus O’Hara) and Lorcan (James Martin) 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. But when the brothers 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.
