FATAL LESSONS: THE GOOD TEACHER is a good made-for-TV thriller. Erika Eleniak plays the homicidal teacher, Victoria Paige, insinuating herself into a typical suburban family in order to destroy them. Said family consists of Dr. Dad, Nurse Mum, the kids, and their loveable dog.
Victoria gets to work right away, undermining the cutesy clan by isolating mum, etc. Vicky also uses her arcane knowledge of all things herbal / pharmacological to facilitate her eeevil agenda. She can incapacitate as well as kill.
If you enjoy movies about psychotic women on a sinister rampage, then look no further! Ms. Eleniak has never been better, except perhaps when she popped out of that cake in UNDER SIEGE!...
