In the courtyards of Trinity College, Dublin, in 1978, aspiring actress Maeve meets pottery student Murtagh Moone. As their relationship progresses, marriage and motherhood come in quick succession, but for Maeve, with the joy of children also comes the struggle to hold on to the truest parts of herself.

Decades later, on a small Irish island, the Moone family are poised for celebration but instead are struck by tragedy. Each family member must find solace in their own separate way, until one dazzling truth brings them back together. But as the Moone family confronts the past, they also journey toward a future that none of them could have predicted—except perhaps Maeve herself.
