Christmas is coming and Bobby and Zena are looking forward to the Christmas holidays. But before that they have the annual Nativity Play. Zena, Connie and Lily are so excited! They've been rehearsing hard and know their parts by heart. They are playing angels and are to be hoisted high into the air above the stage. Gubbi Gudmundsson, who is in the class above them and is a bit of a rascal, is to play the fourth angel, but that's mainly so the teacher knows where he has him. Bobby isn't very happy because he has to be a Wise Man, along with Elmer and Vincent and, as we all know, things don't always go entirely to plan when these three are involved.
