She-Devil (1989)

Funny and witty, this black comedy tells the story of Ruth, a housewife who always looked after her family and supported her husband's success in his career. Suddenly, when he leaves her for a glamorous and successful writer (played by the incredible Meryl Streep) she becomes an authentic devilish seeking vengeance to ease her sorrow. The question is, what will be the limit of that revenge?
