Fed up with Harriet Oleson's (Katherine MacGregor) constant criticisms about her work, Laura (Melissa Gilbert) quits her schoolteaching job -- and invites Harriet to take over. Basking in the opportunity to bring culture to Walnut Grove, Harriet immediately sets up classes in French and art -- totally ignoring such necessary courses as agriculture. Before Harriet's misguided curriculum inevitably results in disaster, Laura has ample time to settle the hash of Ralph (Dennis Dimster), a bully whose pranks are constantly being attributed to the (uncharacteristically) innocent Willie Oleson (Jonathan Gilbert).
