Students in Mrs. Smith's class have forgotten, or never knew, the true meaning of Christmas. From Santa to expensive presents to boyfriends, their explanations of what Christmas means to them are generally selfish and shallow. But that quickly changes when their bus breaks down during a snowstorm and they find themselves seeking shelter in an abandoned church. A homeless man suddenly enters. At first cautious, they soon give him their food, warm coats, shoes and other belongings to comfort him. When he reappears as an angel, he shows them that their generosity is the real meaning of Christmas. The next day the kids write new essays, this time reflecting their new outlook as Christians.
