Rose McNulty (Vanessa Redgrave) has been a patient in the Sligo Regional Mental Hospital for 50 years since being accused of murdering her baby in 1942. The facility is scheduled for demolition. Dr. Stephen Grene (Eric Bana) is a psychiatrist who, at the request of the local Catholic Church, is evaluating whether Rose should be transferred or released. He grew up in the area and has returned to sell his parents' home. Rose is adamant that she did not kill her baby and tells her story to Stephen using the pages of a Bible on which she has written and drawn an account of her life before her incarceration.

Around 1940, Rose (Rooney Mara), an orphaned young woman, evacuates from Northern Ireland to live with her aunt in the Irish Free State, now known as the Republic of Ireland. There, without any intent, she attracts the interest of many of the local men. She has a brief flirtation with Michael McNulty (Jack Reynor), a Protestant who sympathises with the British war effort and soon leaves to join the RAF. She tries to avoid the inappropriate attention of the local Catholic priest, Father Gaunt (Theo James). She dances with Jack Conroy (Aidan Turner), one of a group of anti-British Catholics. Seeking to avoid trouble after a fight between Father Gaunt and Jack, her aunt sends Rose to live in a deserted farmhouse outside the village.

One day a plane crashes nearby and Rose discovers the pilot hanging from a tree, trapped in his parachute. She cuts him down, discovers it is Michael and shelters him while he recovers, hiding him from the anti-British locals. They grow close and just as he is about to leave they confess their love, have sex, and are quickly married by the local Protestant minister. Before Michael can leave, the anti-British locals seize him from Rose's cottage and later kill him.

Father Gaunt, knowing that Rose had slept with Michael, writes a damning report of Rose's mental health, stating she suffers from "nymphomania". With the permission of her aunt, her only living relative, she is incarcerated in a local mental hospital and there subjected to both insulin shock therapy (insulin coma therapy) and later, electric shock therapy (ECT or electroconvulsive therapy). She discovers that she is pregnant and learns that babies born to single women are given up for adoption or spend their entire lives within the institution. She escapes to the beach. Pursued by Father Gaunt, she swims to a cove where she gives birth. The officer from the Garda Síochána in pursuit in a boat with Gaunt can see Rose striking the ground with a rock and believes that she is killing her newborn son. She was actually severing the umbilical cord with the rock, but Father Gaunt lets the authorities think she is a murderess and takes the baby.

In the present Stephen reveals to Rose's nurse (Susan Lynch) that his own father tried to tell him something about his parentage on his deathbed. He reads a passage from Rose's writing that suggests the baby was born in spring and an official document states 1 May 1942, the same day he was born. Searching his parents' papers, he finds a letter to him from his father revealing that he was indeed adopted and enclosed is a cross from his real father. He then figures out who his real parents are. Stephen returns to the mental asylum and shows Rose the letter. Stephen takes Rose to his family home.
