Like every year, Gerald and Gundula celebrate Christmas with the whole family. But Christmas Eve turns into a disaster in which Gundula loses his nerve. It was not to be expected that her mother and mother-in-law would warm up the old stories and that her husband Gerald would not even be able to put up the Christmas tree. Gerald didn't want to have Christmas with the family from the start. Gundula's religious brother Hadi and wife Rose are notoriously annoying.
