It starts out with some clear warnings that the road the wife is on isn't a good one...but she goes anyway because she' sintrigued by the OM.
As the story progresses, the fantasy changes to something very ugly and she realizes after a LOT of damage has taken place that she was really better off walking the other way at the beginning of the film.
The plot content really is mostly about a bad choice made and the chain reaction that results.
You will cry, but affairs are heavily criticized by this film, they aren't dealt with as romantic or humourous, which is the standard approach holly wood takes.
