Biography[]
Beverly Sutphin appears to be an unassuming upper middle class housewife living with her dentist husband Eugene and their teenage children Misty and Chip in the suburbs of Baltimore. However, Beverly is secretly a serial killer, targeting people whom she believes is doing her and her family wrong.
Detectives Pike and Gracey question the family about the vulgar telephone harassment of their neighbor, Dottie Hinkle. Beverly is later revealed to be the perpetrator. Beverly later has a meeting with Chip's math teacher Paul Stubbins, who criticizes Chip's interest in horror films. Beverly gets angry and later runs over Stubbins with her car, killing him. Later, Misty is upset over her boyfriend Carl Pageant standing her up for a date. Beverly spots Carl with another girl at a swap meet, follows him into a public restroom and fatally stabs him with a firepoker. His body is discovered shortly after.
Eugene discovers Beverly's serial killer memorabilia beneath their mattress, which includes recordings from Ted Bundy on the week of his execution. Chip tells the family about his friend Scotty's suspicions of Beverly being a murderer. Beverly departs at that point, intending to kill her neighbors Ralph and Betty Sterner for calling Eugene to treat the former's toothache on a day Eugene and Beverly planned to spend birdwatching and critiquing Eugene's requests for perfect dental health. She stabs Betty with scissors borrowed from Rosemary Ackerman and pushes an air conditioner from their window onto Ralph, killing him. The rest of the family and the police arrive at Scotty's house.
Police follow the Sutphins to church as Beverly is named as the prime suspect in the Sterners' murders. The service abruptly ends when everyone flees in panic after Beverly sneezes on a baby, during which she escapes as police attempt to arrest her. Whilst hiding at the video store where Chip works, she witness a customer, Mrs. Jenson, insult Chip during an argument over a video tape. Beverly follows Jenson home and murders her, but Scotty witnesses the attack. Beverly, having noticed him, chases him through town and into Hammerjack's, where she immolates him during a live performance. The Sutphin family arrive as Beverly is arrested.
Beverly's trial becomes a media sensation. Beverly's lawyer claims that she is not guilty by reason of insanity, but is promptly dismissed. Beverly systematically discredits every witness against her by exploiting their own vices, and is acquitted of all charges. However, having expressed contempt at a particular juror for wearing white shoes after Labor Day, Beverly follows the juror to a payphone and beats to death her with the receiver. Suzanne Somers, who was present during the trial and whom has been set to play Beverly in an upcoming televison movie based on the recent murder spree, angers Beverly into an outburst while attempting to pose for a photo op. The juror's body is then discovered.
