I don't know why other posters refer to Barf Bags and witch hunting in their reviews. I'm pretty sure it has absolutely nothing to do with this film, in which a woman, after committing a murder in the first scene, flees into a church, confessing her life story to a priest.
It is this story of hopeful marriage, the indignities brought on by her ambitious husband, and her vow to raise her daughter sheltered from the corruption of the world of men, even if it means damning her own soul.
Of course, nothing as extreme as witchcraft occurs. She gets the nickname 'Doña Diabla', or Madam Devil, mainly for her reputation for seducing men and ruining their lives. She becomes a shrewd manipulator and a skilled businesswoman. She gets involved in adultery, shady financial deals, marriage-breaking, leading others to ruin and even driving a woman to suicide. Of course the film redeems her because she did it all to provide her daughter with a decent, wealthy life.
It stars the glorious Maria Felix, a woman suited for a close-up, if there ever was one. Films like this made her reputation as a headstrong diva that was willing to play in the world of men by her own rules. This of course made her a National Legend, and she was the most popular actress in Mexico's Golden Age.
Of course.. this film has nothing to do with witchcraft, barf bags, or even nudity, this was after all, filmed in 1950!. I can only try and guess what those other posters had on their minds!!
