Inside Out
Inside Riley Andersen's mind, five personified emotions—Joy, Sadness, Fear, Anger, and Disgust—guide her reactions from their control center, Headquarters. When Riley's family moves from Minnesota to San Francisco, her world is upended, causing Sadness to accidentally contaminate a core memory, which are the foundational memories powering Riley's personality islands. In a struggle to contain the memory, Joy and Sadness, along with all of Riley's core memories, are ejected from Headquarters and embark on a perilous journey through the vast, intricate regions of her mind, including Long-Term Memory, Imagination Land, and Dream Production. Back in Headquarters, Fear, Anger, and Disgust attempt to steer Riley, but their efforts lead to her becoming increasingly despondent and detached, causing her personality islands to crumble. On their quest to return to Headquarters, Joy and Sadness encounter Bing Bong, Riley's forgotten imaginary friend, who sacrifices himself to help Joy escape a memory dump. Joy eventually realizes the crucial role Sadness plays in allowing Riley to process grief and receive comfort, and upon their return, Sadness is able to help Riley openly express her sorrow to her parents, leading to emotional healing and the formation of new, more complex core memories that combine multiple emotions.
