Plot.
Riley Anderson is an 11-year-old girl. She moves from Minnesota to San Francisco with her family. This affects a number of emotions in her head that each control her feelings, thoughts, and memories. The five emotion characters are: Joy, Anger, Disgust, Fear, and Sadness. Each of the characters has power over an island of Riley's life, which represent different parts of her personality. 
After a bad series of events at her first day of school, Joy and Sadness get sucked out of Headquarters, where the 5 emotions work. The rest of the movie consists of the other 3 emotions trying to compensate for Joy's absence but failing to.
Near the end of the movie, after Riley tries running away out of homesickness, Sadness and Joy come back. After every emotion tried discarding Sadness in the past, she stops Riley from going back to Minnesota. Riley then goes back to her new house and cries about missing her old home with her parents, with Joy and Sadness in control. After she finishes crying, a bittersweet yellow and blue memory comes out, made by the both of them. This is Riley's first mixed-emotion memory. This memory makes the emotions realize that Sadness also plays an important role in Riley's life.
