How ha's life being turned inside out

Riley (Kaitlyn Dias) is a happy, hockey-loving 11-year-old Midwestern girl, but her world turns upside-down when she and her parents move to San Francisco. Riley's emotions -- led by Joy (Amy Poehler) -- try to guide her through this difficult, life-changing event. However, the stress of the move brings Sadness (Phyllis Smith) to the forefront. When Joy and Sadness are inadvertently swept into the far reaches of Riley's mind, the only emotions left in Headquarters are Anger, Fear and Disgust.

Inside out and back again is the book, and Ha's life is turned inside out because at her new school, she is being bullied, when she has never went through any of this before.
