Veteran Hollywood leading man John Beal guest stars as Mason Beardley, an old friend of Grandpa Walton (Will Geer). When Grandpa's family offers to fix up Mason's house, he is delighted, jubilantly declaring that it will be perfect for his wife, whom he expects to show up on the Mountain at any time. But there's something very odd about Mason's obsessive devotion to his missing spouse...and it takes the intervention of his son James (George Garro) to clear up this oddness. Meanwhile, Elizabeth (Kami Cotler) causes havoc in the Walton household when she insists she has an invisible friend.
