 At the age of eleven, Riley and her parents move to San Francisco for her father's new business. Riley has poor first experiences: the new house is cramped and old, the moving van with all their belongings was misdirected, her father is under stress from his business, and a poor encounter at a pizza restaurant leaves her disheartened. When Sadness begins touching Riley's happy memories, turning them sad, Joy tries to guard them by isolating her. On Riley's first day at her new school, Sadness accidentally causes Riley to cry in front of her class, creating a sad core memory. Joy, panicking, tries to dispose of it, but accidentally knocks the other core memories loose during a struggle with Sadness, deactivating the personality islands. Joy, Sadness, and the core memories are sucked out of Headquarters, and taken to the maze-like storage area of long-term memory.
