Christmas is in the air as teen-age twins Chris and Susan Pratt head to their grandparents' house in a charming, snow-covered village in Vermont. But the girls do more than engage the entire town in a festive holiday celebration. With their usual cleverness, they use their identical appearance to solve a mystery that threatens to close the local children's hospital.
