One of the women gets sick when her boyfriend kills himself. She moves to a retreat in the middle of a beautiful Japanese landscape. She ends up killing herself too, but not until about two hours into the film. The male lead kind of has to choose between this woman with all the psychological problems, and another beautiful young woman who is sort of is and sort of isn't available, so it's very difficult for him.
I kept thinking that Bergman would have done something much better with the script which meandered around and around and didn't go very far- possibly handicapped by the fact that it is based on a novel- and he would have had better dialogue (it was very vacuous at times), and he wouldn't have worried about the beautiful settings, because his script and actors would have been able to sustain something great without it. Maybe I'm getting old, but all the young people talking about erections and periods and so on didn't particularly interest me.
So I was glad when the film finally ended, even though everything about it was easy on the eye.
