Plot

Jenna Rink, a girl celebrating her 13th birthday in 1987, wishes to be 30 in hopes that it would help her overcome her unpopularity at school. Jenna especially wants to join the "Six Chicks," a school clique led by Lucy "Tom-Tom" Wyman, who takes advantage of Jenna's desire to fit in by manipulating her. Jenna's best friend, Matt Flamhaff, gives her a doll dream house he built for her and a packet of "magic wishing dust" for her birthday.

Tom-Tom dashes Jenna's hopes of joining the Six Chicks by pulling a cruel practical joke on her during a game of "Seven Minutes in Heaven." Jenna, mistakenly thinking Matt was responsible, gets angry with him and, unknowingly sprinkled with her doll house's magic wishing dust, wishes to be "thirty, flirty and thriving." Seconds later, Jenna awakens as a 30-year-old woman living in a Fifth Avenue apartment, without her friends or family. It is now 2004, but Jenna has no memory of the 17 years that have passed since her 13th birthday.
