Riley is an ordinary 11-year-old schoolgirl, and as at each of us, her behavior is defined by five basic emotions: Joy, Grief, Fear, Anger and Fastidiousness. Emotions live in consciousness of the girl and every day help it to cope with problems, directing all her acts. For the time being emotions live in peace and friendship, but suddenly it turns out that moving from the small cozy town to the noisy and crowded megalopolis is necessary to Riley and her parents. Each of emotions considers that it is better other knows what needs to be done in this difficult situation, and in the head of the girl there comes the cock-a-hoop. To adjust life in the big city, to accustom to new school and to make friends with schoolmates, Riley's emotions should again learn to work together.
