The Christmas story, presented in the form of a medieval York mystery, or miracle play, by a cast of junior school children. They follow the text, in verse and prose, used by strolling players five centuries ago when a miracle play meant the portrayal of the mystery of Christ's birth. The story is divided into scenes, with costumes and settings patterned after biblical times. Between acts a children's "angel choir" sings familiar Christmas carols to introduce each scene.
