Detective Sergeant Margaret "Magnum" Schultz has been a cop with the Porterville Police Department for ten years. The old adage "a woman has to work twice as hard as a man to get half the credit" may apply, not only because Schultz tops out at five-four but because not all the men she works with think she should be there.
A hooker is found strangled behind a local tavern. Magnum goes after the killer. She chases a Dodge Ram out into a muddy field in her Ford Crown Vic. She gets surprised in her own garage by a serial killer, whose last victim was hacked to pieces and fed to pigs. The knock-down-drag out that ensues speaks well of the Model Mugging techniques she uses to survive. Her primary concerns are the safety of her 13 year old daughter and getting the job done well.
