Following Mrs. Lee's indications to find a special flower which may cure Biff, Lassie and the kids look for the home and garden of an aging hermit named Frances. The old woman seems mean and inaccessible and when the kids unintentionally infuriate her, they look like they may be in trouble. Things change when Lassie gives the kids some insight into Frances' true nature and they realize they're perfectly situated to help the old woman find a way to happiness.
