Plot summary
Malcolm and his family go on vacation at a casino on an Indian reservation. Hal is banned from the gambling area after secretly using Malcolm to help count cards for him at a blackjack table. Unable to gamble, Hal looks for another form of recreation and takes Malcolm and Reese on a hike through the desert, where they accidentally wander onto a US Army artillery range, and must find their way back without touching any explosives. Lois wins a day at the spa and shares it with Dewey since the rest of the family is gone. Francis ditches school, thinking he will have the house to himself while his family is gone, only to run into Lois' coworker—and secret admirer—Craig, who also snuck in the house uninvited, and they bond.
