It is Christmas Eve, and it is snowing hard. Annamouse has a lovely tree but no decorations. She tries to walk to town to shop for ornaments, but the snow is too deep. On the far side of the hay field, Willamouse has made beautiful paper chains. All she needs is a tree. But when she sets off to buy one, there is so much snow, she can hardly open her door. Is there a way for two field mice filled with holiday spirit to find each other and make their own cozy Christmas celebration?
