So to sum it up, you drug a girl and make her amputate herself so she won't be able to play the cello for an evil man. And then you tell her to thank you later, which she does, and then you both take revenge on the evil man and live happily ever after.
That's the whole movie. Terrible plot because it just doesn't make sense. Could the main character NOT have done all that and still got the other girl to leave the crazy dude? Probably.
The stars are for the trailer—it was cute—and this would be a great movie to play in the background while you watch another movie on your laptop.
