In reply to Dev.

It does have a story. It's about her realizing where her heart truly is after being in a workplace where she was tired of trying to fit in by being one of the guys (hence the overcoat that she eventually removes). She retraced her steps and found her way back to the one thing that makes her life complete, and that's the love that she shared with the gentleman at the end of the video. Notice he too lost himself after some apparent break up. He was on the wrong track (hence the railroad tracks) and had to find his way back also. It's a very artistic interpretation of the song and I think it works well.
