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.

Gundula Bundschuh longs for a peaceful vacation under the sun of Mallorca. However, her mother-in-law's decision to invite the entire whimsical family thwarts her plans.

The Bundschuh family gets new neighbours, but there the trouble starts for Gundula and Gerald. Brother-in-law Hadi and his wife Rose are the new neighbors and from that moment on everything goes wrong for the Bundschuhs.

The Bundschuhs buy an old manor house, which of course is very popular with all family members. So Hadi and Rose, Ilse and Susanne nest there, but don't even think about helping Gundula with the necessary renovation work. To make matters worse, the monument conservationist von Sternberg gets in the way, who is closely monitoring the renovation work in the listed property.
