Malcolm has been labeled a boy genius and is moved, much to his chagrin, into the Krelboyne class, which is a class full of nerds and geniuses like himself.

Waiting in Lucky Aide for Lois to end her shift, Reese and Malcolm cause trouble, which leaves Dewey unobserved and able to nick something expensive from the store. Lois tries to make a point about "doing the right thing" and loses her job in the process. It also leaves the family with less income, bad food and Malcolm stressed out, especially because he already is in emotional despair over Julie Houlerman. Malcolm gets caught in an awkward social situation and Lois struggles between standing up to the man and providing for her family. Meanwhile Francis gets a break from the academy as honor guard for a beauty pageant. Every cadets dream come true?

Aunt Helen died and the family prepares for the funeral, an occasion that doesn't go as planned. Dewey finds a stray kid, Malcolm tries to avoid going altogether, Reese tries to sink some Evidence with aunt Helen's casket, Francis tries to get involved more into family matters, Hal prepares a speech, Dewey tries to get his new friend Egg home and Lois is all about family obligations. Of course it turns out much different then anybody anticipates.
