 James P. Sullivan (AKA "Sulley") and Mike Wazowski pick up their paychecks at Monsters Inc., the utility company that generates energy from the goose bumps of children. Sulley, the No. 1 scream-generator at the plant accidentally lets in a little girl into the monster world. Since monsters are actually terrified of children it s a major cause for alarm and a major headache for Sulley and Mike.
