The Aylward women are mad about each other, but you wouldn't always think it.
You'd have to know them - in spite of what neighbours might say about raised voices and dramatic scenes - to know that that their house is a place of peace, filled with love, a refuge from the sadness and cruelty of the world.
The head of the family, Nana, is a woman who has buried two sons and whose life has been the family farm.
Her daughter-in-law, Eileen, is estranged from her own parents, having 'shamed' them and given birth to Saoirse.
And then there's Saoirse herself, eavesdropping on lives she cannot comprehend.
It is only when they must battle for the inheritance of Dirt Island - a narrow strip of land adjacent to Eileen's childhood home - that they truly understand the roots that bind their lives together.
