A little girl in Australia finds a dead woman wearing yellow pajamas on a beach, whose head has been badly disfigured or burnt. The police have no idea who she is. Scenes alternate between the police investigation storyline, and scenes from the life of a woman who has a number of different men in her life. How the latter scenes fit in doesn't become clear (or didn't for me) until fairly far into the movie. In fact, I think the other user misunderstood who she was.
This is a fair giallo, but something that really hurt it for me was that there were so many characters who weren't really well identified. From scene to scene I often wasn't sure if I was meeting someone new, or someone from a previous scene.
It isn't without some interest. One memorable scene was when the police put the body into a glass case and put it on public display in an attempt to find someone who could identify her!
Perhaps it was just a flaw in my copy, but it seemed like some short scenes or shots were tinted different colors. There are other scenes where there are clearly intentional changes in colored lights, as when there is an advertising sign just outside a window.
