When Lois buys a brand-new king-sized bed, Hal thinks that her motive is to put more distance between them and refuses to sleep in it. Moved to tears by an opera he sees on television, Dewey is inspired to write his own operatic masterpiece, "The Marriage Bed," which is based on his parents' fight and turned into a school production. Meanwhile, Malcolm and Reese build their own street luge board; and Jamie falls head over heels for the baby girl across the street.

When Hal decides to attend his first annual Neighborhood Association meeting with Malcolm, he is strongly encouraged to take on the role of President. Being his dad's right-hand man, Malcolm sees a perfect opportunity to add some excitement to the community, while Hal's agenda is a little bit different. Meanwhile, Francis takes on a new job as a camp activities coordinator and turns to Dewey for his input on some creative new games. While Dewey revels in his afternoon of fun, his fed-up classmates take their teacher, principal and janitor hostage.
