Plot

Roseanne McNulty must vacate the soon-to-be demolished mental institution in Roscommon, Ireland that she's called home for over 50 years. The hospital's psychiatrist, Dr. William Grene, is called in to assess her condition. He finds himself intrigued by Roseanne's seemingly inscrutable rituals and tics, and her fierce attachment to her Bible, which she has over the decades transformed into a palimpsest of scripture, drawings, and cryptic diary entries. As Grene delves deeper into Roseanne's past, we see her as a young woman, whose charisma proves seductive. We learn that she moved to Sligo to work in her aunt's café, fell in love with a dashing fighter pilot, and that a local priest fell tragically in love with her.
