I haven't seen the film but I have gathered from Chloe's ramblings that it's about two sisters called Elsa and Anna. Elsa has the power to freeze things and manages to cause an eternal winter. Anna has to try and get her to reverse it and restore their relationship. If you've seen the film then let me know if that's not right! The soundtrack sounds great and I am looking forward to it coming it on DVD.
I think it's funny that the film is about two sisters, one whose a blonde and one whose a redhead. However, when I pointed his out to Chloe and suggested she could act the film out with Livia, she told me she would rather be Anna than Elsa. Oh well.
