Dublin, 1918. In a country doubly ravaged by war and disease, Nurse Julia Power works at an understaffed hospital in the city centre, where expectant mothers who have come down with an unfamiliar flu are quarantined together. Into Julia’s regimented world step two outsiders:

Doctor Kathleen Lynn, on the run from the police, and a young volunteer helper, Bridie Sweeney.

In the darkness and intensity of this tiny ward, over the course of three days, these women change each other’s lives in unexpected ways. They lose patients to this baffling pandemic, but they also shepherd new life into a fearful world. With tireless tenderness and humanity, carers and mothers alike somehow do their impossible work.
