Big-hearted Jason (Alan Thicke) hires his elderly friend Jimmy (Douglas Seale) to fix the family furnace, then can't bring himself to fire Jimmy when the poor fellow thoroughly botches the job. Meanwhile, Ben (Jeremy Miller) produces a video about the Seaver family with the help of his classmate Jenny. The last-mentioned role is played by Candace Cameron, younger sister of series regular Kirk Cameron (Mike). ~ Hal Erickson, Rovi
