Deanna has spent her life trying to be a good wife and a perfect mother for her daughter in the last year of high school. However, it seems that her efforts were not enough for her husband who decides to divorce and marry his mistress. Deanna is now in a stalemate for 40 years and without much prospect, she decides to give her a “restart” of life and rejoin high school. What seems to be a perfect idea for her turns out to be a little awkward for her daughter, because Deanna gets stuck in the same high school with her, and her behavior makes her laugh.
