it a coming of age kind of movie, where a depressed teenager spend a great deal of time logging into a site, where the song Mr. Tambourine Man plays(this song plays a lot in this movie), i don’t remember clearly but i think she was stalking a boy who plays the song.
Maybe this will be of some help?
