It's a movie from I think the 90's or early 2000's. A young girl is forced to live with a solider (older man) who is held up in a fort out in the country. He takes care of her but the younger soldiers have sex with her when the come passing by. He builds her a private outdoor pond to bath in. They become very close but not sexual. Anyone know the title of this movie? I think the hot spring or bathing pond may be in the title? Thank YOu
