Now that she's the new teacher in Walnut Grove, Alice Garvey begins to worry about her son, Andy, who is her weakest student. Alice reluctantly agrees to let Nellie Oleson tutor him, but this ends up being a grave mistake.

As the journey from the last episode continues, a woman by the name of Hester Sue Terhoun is prepared to help teach at the new school, and she quickly gets into Joe Kagen's good graces – but not Harriet Oleson's. Meanwhile, Adam reveals a dark secret about himself, and issues concerning racism affect everyone.
