It's an old movie, somewhere in the end of the 80's - beginning of the 90's, it's about a woman who is married with a guy who makes some kind of business deal with another guy but gets screwed and becomes ill and dies. For revenge the wife manages to infiltrate herself into the family of the guy that double-crossed her husband as help around the house and does crazy **** to the family in order to break them apart, she has sex with the son, the mother and the father and manages to play with their minds and makes the wife sick from pills and stuff like that, in order to revenge her husbands death. The woman is tall, blonde very handsome, the wife with the family is a brunette, but I don't remember their names and her son is somewhere around 20 years and the blonde with the dead husband is also the kid's french tutor?

The Hand that Rocks the Cradle?
