Plot
Halley Martin is a young high school student who is disillusioned with love after seeing many dysfunctional relationships around her. Her parents are now divorced and her father has a new young girlfriend she does not care for too much. Her mother is now always alone while her sister is so overwhelmed by her upcoming wedding that she barely exists in the house anymore. On top of that, the shallowness of all the girls and guys at her school convinces Halley that finding true love is impossible. When tragedy strikes, the life of her best friend changes forever - and suddenly Halley is drawn closer to a classmate named Macon.

Mandy Moore cut her hair short because she felt it suited the role; the movie producers weren't happy about it. In the end they compromised and had her wear hair extensions for some of the movie and later had her hair being cut on screen written into the script.Wikipedia
