Two brothers from Wales on a stag night return to a small village in Donegal where they spent a working holiday 16 years previously. There they bump in to an old flame and a series of mishaps and misunderstandings reignite old passions and throw their lives into confusion.
Donal is a 14-year old who develops a passion for greyhound racing. He works in a kennel, which is owned by Good Joe. Good Joe promises Donal ownership of Donal's favorite greyhound, The Mighty Celt, if the animal wins three races in a row. Meanwhile, Donal's mother, Kate, must adjust her life when O, a man from her past, returns. The political climate of Ireland serves as the backdrop of this story.
