Nearing her one-hundredth birthday, Roseanne McNulty faces an uncertain future, as the Roscommon Regional Mental hospital where she's spent the best part of her adult life prepares for closure. Over the weeks leading up to this upheaval, she talks often with her psychiatrist Dr. Grene, and their relationship intensifies and complicates.

Told through their respective journals, the story that emerges is at once shocking and deeply beautiful. Refracted through the haze of memory and retelling, Roseanne's story becomes an alternative, secret history of Ireland's changing character and the story of a life blighted by terrible mistreatment and ignorance, and yet marked still by love and passion and hope.
