When Georgie, Iris and Nola's mother died and their father disappeared into his grief, the sisters made a pact: they would always be there for one another, no matter what. Now, decades later, they haven't spoken for years and can barely stand to be in the same room. As his health declines, their father comes up with a plan. In his will, he states that before they can claim their inheritance, they must spend six months living together in their childhood home in the village of Ballycove, Ireland, and try to repair their broken relationships. As the months progress, old resentments boil over, new secrets threaten to come out and each sister must decide what matters more: their pride, or their family. Can they overcome their past and find a way to love each other once more?
