Mike Wazowski (voiced by Billy Crystal), who has been dreaming of being a scare specialist since childhood, finally got into the Monster University Scare School, where countless legendary figures have come from. For this little monster with a pleasing appearance and no terrifying aura at all, studying hard seems to be the only way to realize his dream. In contrast, James Sullivan (voiced by John Goodman), a student from a famous scare school, is the focus of attention of his classmates and behaves like a playboy who doesn't care about anything. Unfortunately, these two guys with completely different tempers provoke the extremely strict dean Dean Hardskribble (voiced by Helen Mirren), and are struck out three times during the midterm exam and expelled from the Scare School. Unwilling to fail, Big Eyes seizes the opportunity and assembles a team to sign up for the scare game held by the fraternity. As long as they win, they will have the opportunity to return to the Scare School. In the arena where many masters gather, Mike and Sulley are about to face unprecedented challenges... This film is the prequel to the Pixar animation "Monsters, Inc."
