When teacher, Miss Beadle, is deemed unable to control some of the rowdy, older boys in her class, Mrs. Oleson convinces the Walnut Grove school board to replace her with a firmer, male hand. But the new schoolmaster tries to bully his students into submission and singles little Laura out as a troublemaker, blaming and punishing her for the slightest infraction even when she isn't the one responsible.
