The movie came out a few years ago I think in 2007-08. The husband is suppose to go out of town for business but really he's having an affair, he's unable to go because him and his wife are kidnapped. The kidnapper has them do things. She has to take something into his work that could destroy his career. In the end they pull into a driveway and it ends up being the house of the woman the husband is having the affair with. This is when it's been revealed it was not a true kidnapping, the wife had it all planned out. Now the husband has to go into the house like it was all intended and murder the mistress.

Does anyone know this movie. All I remember is this and that the wife has blonde hair. I can't remember the name of the movie or any of the actors.

Sounds like Butterfly on a Wheel (http://www.imdb.com/title/tt0489664/)
