All movies starring Ariel Winter

The world goes backwards on Opposite Day. The kids become adults, and the adults become kids.

18-year-old Pauline lives with her family, including younger sister Grace who has Cystic Fibrosis. Pauline has delusions of being a great surgeon, and she also has some horrific dreams that she actually finds "stimulating," to say the least. Her family puts up with her delusions, and her school classmates find her annoying. As this is all happening around her, she has a plan that will leave them all shocked--and some of them may not survive.
