With a bumper crop ready to harvest, Charles and Caroline are delighted with their future prospects until the whole thing is destroyed by a freak tornado which wipes out everything. Naturally, the Ingalls family are devastated, but Caroline, the girls and family friends are stunned when Charles announces that he cannot take anymore of Walnut Grove's disappointments and wishes to return to his family home in Wisconsin.
Needless to say, this side of Charles is one seldom seen and nobody is really sure hope to cope with it as he has always been able to start again before. Finally, it is Caroline who raises his spirits and tells him they will indeed start again - in Walnut Grove. They may have lost everything but to her, that is no reason not to put everything back together again and pick up the pieces. Which is exactly what they do. A lesson for us all and a fantastic episode for all "Little House" fans.
