Angela Fischer (Barbara Mandrell) is put in a very uncomfortable position when her son Steve (Jonathan Scarfe), who has recently weathered a number of emotional difficulties, returns home with his new girlfriend Kelly Garner (Zoe McLellan) in tow. Although Steve is entranced by Kelly, Angela has a bad feeling about the girl, whose past is a matter that clearly disturbs her. As it turns out, "mother knows best," as the seemingly angelic Kelly precipitates deadly havoc throughout the Fischer household. With this made-for-TV film and the previous Stranger in the House, actress Zoe McLellan inarguably cornered the market in playing baby-faced psychos! The Wrong Girl debuted January 4, 1999 on NBC.
