The film starts when Joel was going to the station. In the middle of the way for his train, he changed his destination, and went to Montauk. Was Valentine's Day, and in the way of Rockville Center, his town, he met a girl, called Clementine. They became friends, and then, the film really starts. I will not tell what happened, because it's a spoiler, so, I have to say that it's a great movie, and you can cry seeing this. I really loved it.
