The show starts out with Adult John Boy giving the narration. He talks about how they would get their news on Walton's mountain, that he remembers when he was about 17 and some people came that showed him a glimpse of the outside world.
We open up in the kitchen where all the children are counting up money; they earned it and saved it up to go to the Carnival. They cheer when John Boy tells them that not only do they have enough for the Carnival but they have enough for a stick of cotton c andy. Meanwhile Olivia and grandma are doing some work in the kitchen, when the kids go upstairs, John Boy goes back to collect the money. Grandma washing the table knocks her glasses off and they shatter, John Boy picks them up looking at them. The glasses would cost two dollars to fix, and the families emergency money was spent on Jason's shoes. Olivia thinks about paying for them some other way, but grandma refuses saying if that if the Walton's cant pay with cash they do with out.
All the children are in the bathroom getting ready. John Boy tells them that Grandmother can't do much with out her glasses. He tells them that the money is all of theirs so he can't tell them what to do with it but that he is giving his share towards grandma's glasses. Eventually all of the Walton Children agree to give their share, despite being disappointed that they will miss the carnival. John Boy goes downstairs to tell her; at first she wouldn't have it. Claims her eyesight is good, John Boy and Olivia looking at her oddly, then grandma knocks a tin off the table
We see Elizabeth staring at a Carnival poster in awe, outside the general store. Mary Ellen, Jim Bob and Elizabeth enter; Ike asks them how they liked the carnival. Jim Bob says "we didn't go Mr. Godsey" Elizabeth "Grandma broke her glasses and we have to send a money order …" Mary Ellen hushes her and asks for the money order. They go to set it up , a girl enters the store she picks up a soda commenting on the Walton's not having been at the carnival, how exciting and sarcastically tells them she is sorry they missed it.
John Boy and Olivia are outside working on their clothes hanger. The Sheriff drives up and tells them that the carnival manger took off with all the money and that four carnies were still in the area. He has heard they have no respect for people's property he suggests they lock everything up. Olivia wants John Boy to keep any extra eye on the children till the carnies are gone.
John Boy is reading aloud to Jim Boy and Elizabeth, after he finishes he picks Elizabeth up and puts her on her bed. John Boy is then seen writing in his journal about how he didn't want to ask his siblings to give their share of the money, especially his youngest who cant understand as well, he leans back in his chair.
A shadow of a monkey, Jim Bob in bed sits up looks out the window where the monkey sits, he climbs out of bed and goes to the window, he calls for Elizabeth, who comes over and looks out with him. We go back to John Boy and his thoughts, a train whistle in the distances, he talks about it giving him a restless feeling he doesn't understand, he quickly gets up and starts to pace a little.
We come back to the kids and the monkey, Jim Bob is attempting to open the window. John Boy hears the noise from his bed room window and goes to check it out. Jim Bob still struggles with the window as John Boy comes in. "Now what are you two doing?" he questions them. John Boy looks out the window but the monkey is gone. He tells them to get to bed before they get into trouble. We see the monkey seating on the roof, a figure runs up in the shadows and whistles, the monkey goes to the person and they walk off.
At the kitchen, John Boy, John and Grandpa are at the table. John Boy is reading a magazine about the Worlds Fair in Chicago; he'd like to see it.

The monkey comes down and takes a piece of food from Jim Bob's hand. John Boy is shown looking for Jason, Jason calls him over and John Boy questions them if they have seen any strangers a bout, Jason says "No, just the monkey" and points at it.
