While their termite-infested house is being fumigated, the Seavers seek out another place to spend the weekend. Unfortunately, Jason (Alan Thicke) misplaces his wallet and is unable to rent a motel room--and even more unfortunately, his mom Irma (Jane Powell) is unable to put the family up due to a meeting of the Jerry Vale Fan Club (guess who shows up as "himself"). Ultimately, the family takes up temporary residence in the tiny apartment of their son Mike (Kirk Cameron)...an experience that will remain etched in their psyches for all time!
