When a new boy from a wealthy family begins school in Walnut Grove, he immediately begins causing as much trouble as possible for Miss Wilder and the other students. Miss Wilder finds him so impossible to deal with that she feels expulsion is the only answer but the school board don't want that to happen so, upset and angry, she decides to pack her bags and leave.
Laura becomes directly involved when 'Bart the Bully' attacks Albert and she decides that as Miss Wilder can't seem to control the boy, it's going to be up to herself and Albert to deal with him.
This results in a delightful episode, and one that should not be missed. Miss Wilder and Almanzo are always gems to watch and it's good to see some 'kid power' taking hold of a negative situation and turning it around instead of just the adults for a change.
