In the end, Joanna is murdered by one of the Stepford wives, and in the final scenes of the novel, the reader sees that Joanna has become obedient, complacent and replaced by a female android who is the perfect wife and mother in every way.
However, while in Stepford, Joanna becomes disturbed as one by one, her friends become more obedient and picture perfect in every way.
In the story, Joanna moves to Stepford, Connecticut with her husband and children, eager to get away from the hustle of big city life.
One example of taking the concept of female robot, fembot or gynoid one-step further was Ira Levin's novel, The Stepford Wives.
Faith Hill had a supporting role in the 2004 version of The Stepford Wives.
I know "The Stepford Wives" is meant to be a satirical thriller, but I can't help but wonder what would happen if our loved ones were secretly replaced by androids.
