Jean Harris (Bening) is the head of a posh girls' school and the longtime mistress of Scarsdale diet doctor Herman Tarnower (Kingsley), a chronic womanizer. The depressed, pill-popping Jean gets fed up and kills her lover and then endures a sensational trial, which Nagy revisits from both Jean's point of view (a suicide attempt gone wrong) or that she committed cold-blooded murder. The cast is fine but the goings-on get tedious. True crime from the 1980s.
