Resist the temptation to figure out every last detail of this mysterious, poetic film. That way lies frustration. The parts do not quite fit, and anyway this is not a puzzle to be assembled. It is a romance about those moments we all sometimes have when we think we see ourselves at a distance. Is there, we wonder, more than one me? It's about two young women who never quite meet. One lives in France, the other in Poland. They were born on the same day. They have identical heart problems. They are both wonderful singers. One dies, the other doesn't. The movie could have been truly confusing if it cut back and forth between the two women, both played by the same actress, but it doesn't. It follows one then the other.
