Cecilia , a woman of devout faith, travels to Italy to begin working in a prestigious convent in Italy that treats nuns nearing the end of their lives. While at first, the convent is picture-perfect and the priest seems welcoming and friendly, it soon becomes clear that the convent hides a terrible secret and that Cecilia's arrival was seemingly preordained...
Although 'Immaculate' has all the hallmarks of a grisly horror with Sydney Sweeney cast in the role of scream queen, there are a lot of thematic similarities with Sydney Sweeney's own life that bubbles right under the surface. Namely, a lot of men being very, very weird about Sydney Sweeney's character's body, and why her character goes along with it until she doesn't.
For much of the movie, Sydney Sweeney's character is surrounded by men and women - mostly men, doctors and priests especially - who view and treat her at first with an overbearing hospitality, but then shifts into a reverence that quickly veers into obsession. It's not even so much her as it's what she represents, and though the obsession is made up of supposed religious piety, it's still about controlling her no matter what and her fulfilling her duty.
