Iam looking for a movie where a girl gets kidnapped?

ok the girl is a the daughter of some rich dude while she riding in a limo her driver pulls up to the men who kidnap her. One of the kidnappers is given the job to watch her throughout the movie the two fall in love with each other. the movie ends with the girl ride in a limo and she thinks she is about to get kidnapped again but its really the kidnapper that's she fell in love with
