In the conclusion of a two-part story, Laura (
Melissa Gilbert) tries to get over the departure of her fiancé, Almanzo (
Dean Butler), by helping her sister Mary (
Melissa Sue Anderson) and brother-in-law Adam (Linwood Boomer) set up a new school for the blind in the town of Sleepy Eye. As fate would have it, this is the same town where Almanzo has relocated -- and when she sees her beloved in a compromising situation with a saloon gal, Laura angrily breaks off her engagement. Things change dramatically when Laura discovers a remarkable secret about Almanzo while nursing him through an illness. And Laura's father, Charles (
Michael Landon), is prompted to reconsider his insistence that the girl wait until she is 18 to get married. But what of the still-blossoming romance between Nellie Oleson (Alison Arngrim) and Percival Dalton (
Steve Tracy)? This was the final episode of
Little House on the Prairie's sixth season. ~ Hal Erickson, All Movie Guide
