Confused murder suspect cannot remember if she murdered her rich husband.
Against the better judgment of hard-bitten "throw the book at her and save tax-payers' money" type police department, smooth psychologist/hypnotist (Nigel Hawthorne) helps her to relive the night of the murder by means of regression into her past.
However, as she relives life with her husband she begins to notice that lots of details don't quite match her memories. What really happened?
This is NOT a fantastic film, I wouldn't pay money to see it in a cinema, for example. The depiction of hypnosis is bizarre enough to initially seem quite funny.
Once you get over that rather shaky plot device though, the various layers of reality brought up by the hypnosis are quite interesting in a "what is reality?" way. It reminded me the teensiest little bit of "Memento" and even though it was late at night I ignored the film's more pretentious angles and sat through the entire thing. Mainly to see why the memory discrepancies occurred and so on.
The lighting and photography are also quite nice.
