In the case of Savanna and Gracie, friendship isn't based on reason, but
on the notion that opposites attract. Savanna is a head-turning,
attention-seeking, accessorized one of "Those Girls," while Gracie's
love of old movies and commitment to protecting the environment put her
into the "everyone else" category. It seems as if nothing could come
between them until Savanna's lies and dependence on Gracie as a false
alibi start to take a toll on their relationship. When Savanna gets
between Gracie and her crush, the line separating best friend from worst
friend is crossed.
