Wicked

Julia Stiles is an evil teenage girl who stops at nothing to get what she wants. Julia Stiles is Ellie, an average teenage girl with typical teenage problems: a bratty little sister, a nagging mother who's having an affair with the next door neighbor and a father that denies her the attention she so desperately craves. She doesn't find much to be happy about, at home or at school. But Ellie's not the kind of girl who gets mad. She's the kind of girl who gets evil. (official distributor synopsis)
