40 year- old wife and mother Claire Carenberg is unhappy - with herself, her age and with everything in general. Her two teenage kids are distancing themselves from "Mommy" and she has reason to believe that husband Frank, teacher at local High School, might be having an affair with a student. But through a "magic spell" Claire's life changes from one moment to the next: she is suddenly 16 again and is given the opportunity to return to school as a younger version of herself. This way, she invisibly gains access to her children as well as her husband. But the weeklong absences of her "old self" put an immense strain on her family: Claire is forced to watch as things fall more and more out of balance.
