Innocence

French film which I'm sure has some sort of symbolic meaning which I can't figure out. Young girls arrive at this "place" in a coffin. They are greeted by their housemates who are age-indicated by the color of ribbon in their hair. The eat together, play together, work together, dance together, learn together, and sleep together. At night some of the girls disappear and it's very mysterious. No one comes to visit them and they have no contact with the outside world. The houses all play together, so there are all kinds of inter house activities, but they're not allowed out of what appears to be this school compound. If you try to escape or disobey, you are punished by being forced to serve the girls for the rest of your life. So once the girls are old enough, they are put on a train and sent into the city. Not sure exactly what this signifies, but I'm guessing it's some sort of coming of age story (which never make sense to me anyway). Decent movie, but really doesn't have enough direction (point A to B) for me.
