This is a very intimate exploration of the female psyche, but at the same time it's barely a film. Naked women in South Estonia spend time in a sauna sharing their secrets and pains and thus ritualistically cleansing themselves of them. An interesting concept, I would say especially for young people who have not been exposed to these kind of stories or had never had the opportunity to feel understood by peers and might learn something. There is some beautiful scenery and traditional and mystical rituals that are filmed very nicely, too.
However nothing else much happens. If you are in the mood to hear these intimate stories of childhood trauma, love, teen love, abortions, rape, violence, mother daughter relationship, lesbianism, body image issues and so on, this is a great film for you. Yet at the same time it can be considered a loose collection of short female confessions that can be read separately, like a series of blog posts. My wife absolutely loved it. I felt it was not for me, although I appreciated it the format.
The sauna in East Estonia and Finland and those areas is not merely a thing you do for pleasure, but has deep roots in their old culture, even pre-Christian and may have roots in rituals in the Neolithic. The film touches on that through scenes that show what is being done, but without any explanation. Read about it, it's fascinating.
Bottom line: it's a film for women.
