The Walton children find that it really isn't easy having their mother as a substitute teacher whilst Miss Hunter is on her honeymoon, especially Elizabeth who has never had to share her mother with so many other children before. When a young man comes to school whom the other children call slow and simple, she is distracted even further. During the course of the school lessons she realises that the reason he can't read is because he needs glasses, however his parents are unable to buy them. She does, however, persuade them to pay a minimal amount and buys a very cheap pair for him.
Meanwhile one of John-Boy's old girlfriends returns to Waltons Mountain to sell the old house left to her by her father. She wants the money to invest in her fiancé's new business venture, however John-Boy feels that the fiancé really just wants to marry her for the money she supposedly has.
