Sam Montgomery is a high school senior residing in the San Fernando Valley of California. The tragic death of her father during her childhood left her to be part of her step-family, with a cruel step mother and unintelligent, annoying and self-centered twin step sisters. Her dream is to attend Princeton University, and throughout the film we see her studying for exams, proving she is a hard working student. Sam works at her step mother Fiona's diner, which was formerly her fathers. Her best friend is Carter. Sam is unpopular and rather unknown at school, but has a secret virtual relationship with a boy who goes to school with her, although his identity is not known to her straight away. A 'fairy godmother' comes to Sam's rescue in the form of fellow diner worker, Rhonda.
