Madeline's boyfriend dumps her five weeks before the wedding because she is too structured and rigid. After she has been moping for too long, her sister persuades her that the two of them should go on the planned honeymoon to Niagara Falls instead, since it can't be canceled anyway. In Niagara, Mike works as a guide. Mike hasn't been functioning properly since his girlfriend abandoned him two years ago, and now he is forced by his colleague to take the assignment of guiding Madeline and her sister. It doesn't start well, but over time, Mike challenges Madeline's rigid schedule, and things begin to change.
An average romantic movie. It works even though it is a bit too easy and doesn't offer much in terms of challenge or depth.
