Everything is normal with the Krumborg family – but when you know them, nothing can surprise you anymore. The two robbers Boris and Ivan want to kidnap Krumme. Krumme wants to learn to ride a horse. Mom wants a healthy Christmas. Dad doesn't want a healthy Christmas. And it's hardly surprising that Krumme's Christmas present for Yrsa ends up under Mrs. Olsen's bed, or that caretaker Svendsen tries to repair Mrs. Olsen's sink – even though it's not broken. And the youngest member of the family, Grunk, has eaten all the Christmas decorations. Yes, everything is completely normal in the Krumborg family...
