A heavy rain has been falling in Walnut Grove for two months, and it shows no signs of stopping. Farmers like Charles fear that their families will go hungry, and after reading an article in the newspaper, they take a 400-mile journey with their wives and children for a temporary new life in Gold Country. Things start out pretty well when Charles and Isaiah dig up some gold, but Laura and Carl get a completely different perspective from a new friend that they meet near their camp site. Meanwhile, Caroline opens and teaches a school in a tent, right in the middle of town, but it proves to be a less-than-ideal learning environment for everyone. (thetvdb.com)
