Katoliška Irska leta 1964. Margaret, Bernadette, Rose in Crispina so štiri mladenke, ki so se zaradi nesrečnih življenjskih okoliščin, v katerih so zanosile, primorane preseliti v magdalensko zavetišče, ki ga vodijo nune usmiljenke. Toda namesto usmiljenja so mlade ženske priča krutemu nasilju in norčevanju avtoritativne sestre Bridget, za katere nežno pojavo in milim glasom se skriva prava sadistična pošast. Dekleta se dobro zavedajo, da bodo iz samostana prišle le s pobegom, zato združijo moči in se odločijo ukrepati.
A thoroughly mind-provoking film about 3 young women who, under tragic circumstances, see themselves cast away to a Magdalene Asylum for young women in 1964. One of many like institutions, the asylums are run like prisons and young girls are forced to do workhouse laundry and hard labor. The asylum, one of many that existed in theocratic Catholic Ireland, is for supposedly 'fallen' women. Here, young girls are imprisoned indefinitely and endure agonizing punishments and a long, harsh working system which leaves them physically drained and mentally damaged. As the girls bond together, it soon becomes clear that the only way out of the Magdalene convent is to escape, but with twisted Sister Bridget running the wing, any chances seem limited...
