Jenna Rink has two wishes - to become one of the school cool girls, and to be thirty - rather than be coming up to thirteen and hanging around with uncool Matt. After her disastrous birthday party an accidental sprinkling of magic dust makes both wishes come true and she finds herself at thirty as a highly successful New York fashion editor. Luckily she locates Matt for help on how her new world works, but as she finds out how she has behaved since that birthday party she increasingly discovers someone she thoroughly dislikes.

Jenna Rink is an ultra-adorable naive 13-year old who envies the 'cool' popular girls at school and would do absolutely ANYTHING to be accepted in that group. Her best friend and ardent adorer, Matt, is (in her mind) part and parcel of her uncool persona and (we're led to believe)is an associate she's quite willing to lose in order to gain admiration from the cool set. Before she has occasion to actually dump him, however, a bit of 'magic'(initiated by her heart of heart wish) relocates Jenna into adulthood. She wakes up to find she's thirty, beautiful, a successful magazine editor at her fav publication, and has a hockey-player celebrity boyfriend and (seemingly) all she ever wished for. Of course, as it so often does, life has thrown Jenna some serious curves and dealt her some cards she didn't count on or particularly want. She's become sneaky, selfish, and has virtually rejected her family and the friend (Matt) who meant the most to her in exchange for her 'wishes come true'. As her 13-year-old mentality recognizes her adult 'profits and losses' she is heartbroken and wants only to return to her early teen innocence. And of course, as must be the case in truly 'feel good' movies, she gets her opportunity to make things right. This film is a real heart-warmer, especially for all those who remember the awkward teenage years as well as for all of us who have made poor choices along the way which we wish we could change. Just watching Jenna make good use of that opportunity makes us feel better, allowing us to realize how great it would feel. Written by Janice Brewer
