Synopsis by Hal Erickson
Season eight of Little House on the Prairie is marked with the conspicuous absence of several familiar characters, among them Mary and Adam Kendall and Nellie and Percival Dalton, all of whom have moved from Walnut Grove to New York. Mooning over the departure of daughter Nellie, the insufferable Harriet Oleson (Katherine MacGregor) yearns for a replacement. Before long, the Olesons have adopted a little girl named Nancy (Allison Balson), who looks just like the younger Nellie -- and unfortunately acts like her as well. This is the first episode of a two-part story.
