Extremely well-directed and acted true-life chronicle of Diane Borchardt, a Wisconsin high school teacher who charmed some of her students into carrying out the murder of her husband. Originally shown in two parts on television, the film has the production values of a theatrical feature, and Ann-Margret is nothing short of riveting in the lead. Abandoning her kittenish persona (and all traces of a sympathetic good nature), Ann-Margret is nothing short of chilling in her portrayal of Mrs. B., a cunning and calculating monster. The younger players are also very good and the film is gripping if extremely unpleasant. Difficult as an entertainment, it is still a strong achievement, which is a testament to the talents of director John Patterson and writer Carmen Culver.
