Jane Quimby is a high-school fashionista who works as an assistant to high-powered fashion executive Gray Chandler Murray. Jane's problem is that she got her job because they thought she was an adult so she must keep her true age a secret. Jane soon learns that working for a high-profile executive in the cutthroat world of fashion brings you enemies. In Jane's case, that adversary is India, Gray's former assistant who is now gunning for the executive's job. But Jane has an ally in attractive senior designer Jeremy, who piques her interest even though she still harbors feelings for longtime crush Nick in her "other life" at school. Jane's best friend, Billy, helps her keep her secret as she lives her two lives. But Billy has his own secret that he is keeping from Jane -- a relationship with her school nemesis, Lulu.
