Description

In a world inhabited by monsters, the city of Monstropolis harnesses the screams of human children for energy. At the Monsters, Incorporated factory, skilled monsters employed as “scarers” venture into the human world to scare children and harvest their screams, through doors that activate portals to children’s bedroom closets. The work is considered dangerous, as human children are believed to be toxic and capable of killing a monster through physical contact. Energy production is declining because children are becoming less easily scared, and the company’s CEO, Henry J. Waternoose III, is determined to prevent the company’s collapse.

One evening after work, top-ranking scarer James P. “Sulley” Sullivan discovers that an active door has been left in the station of his rival, Randall Boggs. He inspects the door and accidentally lets a young human girl into the factory. Frightened, Sulley unsuccessfully attempts to return the girl, who escapes into Monstropolis, interrupting Sulley’s best friend and assistant Mike Wazowski on a date at a sushi restaurant. Chaos erupts when other monsters see the girl; Sulley and Mike escape with her before the Child Detection Agency (CDA) arrives and quarantines the restaurant. Forced to keep the girl hidden in their apartment for the night, Sulley soon realizes that the girl is not toxic and her laughter is able to generate more energy than screams………..
