Monster's Inc. in Three Acts

Monster's Inc. is a movie about a monster named Sully. Sully, our hero and protagonist, is introduced to us as the employee of the month at his power plant that specializes in scaring children at night and collecting their screams for energy. All is well for Sully (except for the plant's financial trouble) when the film opens, but things quickly turn when he accidently brings a child back to his world. Children are thought to be extremely dangerous by monsters. She is soon discovered and a frantic city-wide for search Boo (the child) is started. Sully and his friend Mike make the decision to try and sneak her back into her room by returning her at the plant. This decision raises the stakes since they are at great risk of being caught by law enforcement. This is about 30 minutes in.

In act two, the trio is faced with Randall, Sully's enemy at the company, trying to steal the child for his scream extraction machine. The machine will produce more energy and save the company money, but it will harm kids and can only be used after kidnapping them. After a long chase, the trio discover that the head of the company, once thought trustworthy, is really Randall's accomplice. Sully make the decision to try and return Boo despite all the obstacles and expose his boss as a kidnapper. This is the peak of the movie. They are cornered by the boss and it looks as if they are going to lose Boo-and their lives. This act ends about 10 minutes from the end of the movie.

In act three, Sully exposes his boss by recording him saying that he will kidnap children in order to save his company. The boss is apprehended and the child is returned to her room. Everything has turned out well. Even the company, with Sully as CEO, is doing well now that Sully has discovered children's laughter is a better source of energy than screams. This is a Hollywood ending, wrapping up all subplots and the main plot with a happy solution.
