Sister is back with a holiday edition of her ever-popular catechism class. Sister tells the story of the nativity as only she can tell it in this hilarious production destined to become a favorite tradition. Among the mysteries she tackles in her own version of "CSI: Bethlehem" is a question that has intrigued historians throughout the ages: Whatever happened to the Magi's gold? ("We know that Mary used the frankincense and myrrh as a sort of potpourri -- they were in a barn, after all.") Employing her bag of scientific tricks and assisted by a local choir (as well as audience members), Sister will answer this question and more while creating a live nativity scene like none you've ever seen.
