Mary (
Melissa Sue Anderson) accompanies her husband, Adam (Linwood Boomer), on a stagecoach trip to an awards ceremony where Adam will be honored. En route, the coach is involved in an accident in a remote area. As the only passenger who is unhurt, Mary must save the lives of Adam, a pregnant woman (played by
Michael Landon's daughter Leslie Landon), and the woman's unborn child. Meanwhile, back in Walnut Grove, a seriocomic subplot involving Laura (
Melissa Gilbert), Albert (
Matthew Laborteaux), Mrs. Oleson (Katherine MacGregor) and a Christmas fund plays itself out. ~ Hal Erickson, All Movie Guide
