Parallel stories pit Malcolm against Kevin, a bullying, obnoxious new kid who goads Malcolm into beating him up; and Francis vies with his intimidating military-school commandant, who's presenting sex-education lectures. When Malcolm discovers that Kevin is only seven, he is guilt-stricken and tries to make amends by entering a charity marathon race. Meanwhile, Hal chops down the front-yard tree, alienating the neighbors (who can now see the house) but fascinating his sons with the wood-chipper.

Malcolm is a regular high school kid trying to navigate his way through life despite the various obstacles thrown in his way a complete misunderstanding of girls, the constant burden of masterminding plans to get himself and his brothers into or out of trouble, and a miserable job at the Lucky Aide not to mention a severe case of teen angst.
Although Malcolm has a genius IQ, he can't seem to make sense of the opposite sex, much less his embarrassing family. Lois is the outspoken, opinionated mom, who still manages to rule the roost even though her boys are growing wise to her crafty ways. Hal, a dad who is just a bumbling, big kid at heart, often finds himself creating more chaos than his five boys combined.
