Luise wants to celebrate a traditional family Christmas this year instead of going on a skiing holiday with her husband Gideon and their two daughters like in the past few years; she's motivated by a text that one of her pupils, Franz, wrote in class. She invites him to join her in her traditional celebration because he doesn't have a big family. But the relatives come bringing all kinds of trouble, beginning with Luise's egotistical mother Ruth.—Anonymous
