Plot

Beverly Sutphin appears to be a typical suburban housewife living with her dentist husband, Eugene, and their teenage children, Misty and Chip, in the suburbs of Baltimore. However, she is secretly a serial killer, murdering people over the most trivial of perceived slights, including mere faux pas.

During breakfast, Detectives Pike and Gracey arrive to question the family about the vulgar harassment of their neighbor, Dottie Hinkle. After the police and her family leave, Beverly disguises her voice to make obscene phone calls to Dottie, because Dottie stole a parking space from Beverly. Later that day, Mr. Stubbins, Chip's math teacher, becomes Beverly's first known murder victim after he criticizes Chip's interests and questions the boy's mental health and family life, as well as berating her parenting; Beverly runs him over with her car, and is witnessed by Luann Hodges, a young woman smoking marijuana nearby. The next day, Misty is upset when Carl Pageant stands her up for a date. Beverly spots Carl with another girl at a swap meet and murders him in the bathroom with a fireplace poker.
