"Together, a pioneering family faces a crucial test of its courage and its love!"

The day before Christmas vacation started, Miss Beadle lets the children out early when she notices that a snowstorm is beginning. The children aren't able to make it home before the storm starts. The men of Walnut Grove search for the children while Doc Baker takes care of the frostbitten children that show up at the school.
