Needing some alone time, John-Boy hikes up the mountain to a deserted cabin and finds his friend Sarah Jane Simmons hiding, nine months pregnant. Her mother had placed her with a well-to-do family on the promise they would educate her. But they were only interested in using her as a servant, so she ran away and married a young man who went looking for work with the Works Progress Administration. A rainstorm strands John-Boy and Sarah, and he must deliver the baby.

After doing some repairs at a neighbor's home, John is accused of stealing and selling some antique silver mugs. The fact that he was able to buy new tires for the truck doesn't make things any better for him. But John's pride is hurt and he is angry that his integrity is questioned, so he refuses to explain how he was able to buy tires when he had no money the day before the robbery. John-Boy and Ben do some sleuthing to clear their father's name.
