Claudia Lee, 40, is pregnant with her third child, unhappy in her marriage, job, life, body. In the aftermath of a last straw moment that convinces Claudia to file for divorce, she meets Mhairi, a fairy godmother who gives Claudia a magical vacation, returning to life at age 20.

With the confidence of a 40-year-old, and the goddess' body of a 20-year-old, Claudia's teenage dreams come true as she gets a chance to do all the things she can't in the future and couldn't in the past.

But Claudia soon learns from Mhairi that her life trajectory has unexpectedly changed, threatening her children's existence, and now she has one week to fix her future, which might mean breaking some hearts - including her own.
