Agnes of God?
I don't know a ton about this movie yet, but from what I've heard so far it sounds a lot like Agnes of God, a play about a psychiatrist who's investigating this young, somewhat crazy girl named Agnes who's an incredibly devout Christian. Agnes ended up having a baby and the psychiatrist has to figure out if Agnes killed the baby or not.
Does anyone know if it the movie's based off the play, because it'd be really interesting to see and compare and contrast if it was.
