Plot summary
Malcolm's first day of high school gets off to a bad start when Lois embarrasses him in front of the entire school, causing him to have no friends except the Krelboynes. He tries to commit an offense that would make Lois send him to military school, but Cynthia warns him that if he does so, she will 'never have sex with him again', lying and sacrificing her own reputation to restore his. Lois and Hal volunteer in the school, where Hal clashes with Mr. Herkabe. With Malcolm and Reese away, Dewey stays home alone for the first time in his life and has a wonderful time. On the ranch, Francis is overwhelmed with the workload due to Otto constantly allowing his employees to take extended vacations. Just when he is about to quit, Otto gifts him a truck, persuading him to stay.
