Standish dupes Toby into losing all his money using cards and drink at the saloon. Everything comes to a head as the fireworks go off in the saloon. The Ingalls, Olesons, and Garveys get tired of the bustling city life during all this (Nels getting drunk and wins a whole pile of money), and they decide quickly to return to Walnut Grove. The Ingalls take Albert along with them.

Charles and Albert travel with the Cooper family while on a delivery. A serious accident occurs while the Coopers are going down a steep hill. The Cooper parents are killed. Charles tries to find Cassandra and James a new home. When he can't find anyone to take them both in, he feels he has to send them to an orphanage.
