The Girls' Room (1999)

Casey and her dorm mate Grace are complete opposites. The determinedly polite Grace wants to follow the Southern Belle Rules: graduation, the "perfect wedding" to the "perfect Southern gentleman" and a house built by Daddy near the club. Casey is a loner, smart but hardened by her troubled past and the parents who walked out on her. Casey doesn't know what she wants -- except to stop living with Grace. She tries her best to torment Grace any way she can, but one day she goes to far, and Grace decides that it's time to "right the balance" -- even if it proves to be her own undoing.
