Malcolm's older brother, Francis just escapes from his Military school and comes back home to see his girlfriend, Beebee.
In the cold opening, Malcolm, Reese and Dewey are quietly sleeping, when Lois rips open the curtains and tells them breakfast will be off the table in five minutes.
Francis decides to go on AWOL from military school to come back home with his ditzy girlfriend and dream of about them running away to Canada. It is revealed that she is a thief and that does pays no attention to Francis whatsoever while Malcolm was giving her a letter from Francis.
Francis escapes from school and hitchhikes back home. Malcolm finds him in the backyard, hiding. Francis convinces Malcolm to help him and give some instructions and a letter to Bee Bee. While the family is eating later, the phone rings. Lois answers and exclaims that Francis has escaped. Malcolm assures them he is okay, which makes Lois question what he knows; Malcolm squeals under pressure. Malcolm tries to distract Lois by saying that Francis met Beebee at a park near the soccer field.
Francis says that he loves Beebee because no one else has ever loved her. When Dewey overhears Malcolm and Francis talking in the back yard, Malcolm convinces him that Bigfoot is out there to scare him away from there.
When Francis sees Beebee, she heartlessly breaks up with him. He is left humiliated and stupified. His hopelessly romantic antics had not succeeded on her. As he lays crying in the dirt, Dewey hears the moaning and thinking that it is Bigfoot, throws rocks at him, later making up a story to Reese, about him slaying the monster, befriending it, and getting slurpees with it. Lois goes on the wild goose chase for Francis, and ends up accosting several other horny teenagers making out in the park about love and their stupid behavior.
Later on, Malcolm is sitting at the dinner table snacking on crackers and then he goes to his bedroom and sees Francis standing their in the doorway, cleaning off and explaining that Beebee broke up with him. Francis says goodbye to his brother Malcolm and packs his bag and hops out of the window so he would walk down the street, when a car pulls up behind him to offer him a ride so it turns out to be his father Hal, who found him on the street only because of Malcolm ratting him out once again. Hal is sympathetic with Francis and tell him that they will call Lois after they put a few states behind them.
