As Diana Borchardt, a sociopath and schoolteacher who tires of her husband and wants out; this is a very interesting study of what some people are capable of.
Peter Coyote is sympathetic as the victim, Ruben Borchardt; as she calls him "Rube the boob"; she is an emasculating, narcissistic woman, (not schizophrenic as a previous review intimates).
The fact that this was based on a true story makes this all the more relevant, here was a well-liked teacher, popular with the students, capable of unbelievable manipulation, malice and murder.
The murder of Ruben is carried out by several students, who believe Borchardt is being physically abused by her husband (She was not, but concocted this story to acquire life insurance benefits). Tobey McGuire in particular is rather sympathetic as Ruben Borchardt's young son.
Borchardt apparently even visited her in-laws for Easter, knowing that their son was just brutally murdered, to cover up her role in the homicide. The students were pawns, part of her intent to control.
Indeed, no one even benefited from Ruben's death. The house was tied up in debt, and Diana Borchardt never paid the students what she had promised. She thereby perpetuated the psychological theory that there are some sociopaths who subconsciously want to be apprehended for their crimes. 8/10.
