For some unexplained reason, letters to Santa Claus are being returned to the children of Junctionville. It seems some sour soul has angered St. Nick, calling Christmas "a fraudulent myth!" The skeptical rodent Albert Mouse has to be brought to his senses "and let up a little on the wonder why." How Albert is persuaded to change his tune paves the way for Santa's jolly return to Junctionville in 'Twas the Night Before Christmas. After Sister Theresa (voiced by Angela Lansbury) rescues an orphan shepherd boy from a lightning storm, she lovingly nurses him back to health. However, the boy suffered injuries during the storm and wakes up blind and discouraged in his new surroundings. With Sister Theresa’s help, the pint-sized shepherd with the king-sized heart learns that seeing goes deeper than what your eyes show you. Together, they discover that unconditional love can overcome any obstacles in The First Christmas Story.
