Heather Locklear, best known for TV hits like "Dynasty" and "T. J. Hooker", shows she's more than just a pretty face here, giving a devastating performance as a housewife and mother of two girls who suffers from multiple personality disorder. Her condition stems from somewhat obtuse daddy issues in her childhood, which come to a head in the surprisingly intense climax. Despite a few over-the-top flourishes, this a tough, non-campy effort from the "Sybil" school, offering its leading lady a rare opportunity to do serious work. Director Stephen Gyllenhaal really gets into the heroine's scrambled mindset, with jagged editing taking her from morning into night into the next afternoon into the following morning. The ominous plot-thread with Locklear's father, who was involved in some dirty financial dealings, isn't made quite clear, but Locklear is fully invested in her character and the film has a nice gritty look.
